‘Hola’ is a Spanish word that means Hello in English. Spanish is a language that used by the great Roman emperors and the greatest achievement in their history and cultural is associated with the deathless of the language. People who know English language can easily learn Spanish as it written using Latin alphabets. 28 characters are use in Spanish writing. And all most all are like English letters. The pronunciation of Spanish words a little difficult for people who’s mother language is not Spanish. They give more stress on proper pronunciation of Spanish vowel. There is inheriting relation between Spanish and Arabic. It sounds like Arabic when a Spanish man specks the language fluently. We know Spanish is a original language of Spain – one of the greatest country of Europe. The language expands its geographical allocation around the world. Especially in Latin American countries like Argentina, Mexico and Costa Rica, Cuba and many other small countries along the shore of Pacific Ossian. Even in America the Latin American people love to use this language in daily life and official requirements. In Asia Spanish is the official language of the country like Philippine. Various universities in Argentina, Mexico only allow a student for admission if he or she is sound in Spanish. Sometime s there is on gaps between the study course and the students due to language problem and gap year volunteer helps to fill up this. The foreign students who want to get a foreign degree in Arts, Science, Medical Science and Management form a South American University Needs to learn the Spanish language. Spanish speaking US people are very large in North Americans countries. Spanish immersion Argentina is a special program for learning Spanish in Argentina and a lot of foreign student are learning this languages with the help of their dedicated experts. The students who want to starts their career in the USA after completion of graduation needs to learn the Spanish language. One of my friends wants to do his MD in Medical science in Argentina. The face difficulties as he don’t know that languages. He got some institute for learning Spanish language as a foreign student and that institute helps him to learn Spanish South America. They help to learn the style of Spanish language and it grammar, and pronunciation that are essential to learn any language properly. Learn Spanish with the help of a group of experts.

Electronic and the science of electricity both deals with electricity and both electric current. The use of electricity has a direct relation with environment. Electricity deals with current mainly as a form of energy that can operate light, electric motors and other equipments. Electronics treats electric current chiefly as a means of carrying information. Current that carry information are called signals. The electronic devices are made of various electronic parts. The main function of the electronic parts is to change a current’s behaviors to produce or modify signals or in other word, interpreting the signals. Development of electronics parts make our eclectic goods more energy saving. There are thousand of Electronic Parts are available in the electronic marketplaces. Earlier electronic circuits were connected by means of wire. The various connecting wires got jumbled up and it give rise a problem of inter-electrode capacitance that changes the circuit characteristics. Apart from this, it was very difficult to test and repair the particular electronic circuit. Thus, in order to cover come these difficulties printed electronic circuit are introduced to connect various electronic parts. The printed circuit boards are simply known as P.C.B. It is an insulated Bakelite sheet printed with a circuit of electronic circuit diagram. There are various electronic parts are available in the market and even online like transistor or Tr, variable capacitor or VC etc. These help to remove the problem if inefficient energy uses.

The Resistors are converts the electrical energy into heat energy and there are different kinds of Resistors are helpful for different electronic uses. Some Resistors are fixed valued and others are variable valued. The heating elements are also known as resistors and they help in transmitting using electric energy. There are some interesting resistor are available as Tharmistor. They can change their resistance power with the change of any change in the temperature of its environment. Various electronic companies make electronic parts with different parts numbers. Semiconductors are just other insulators if they are very pure and especially at very low temperature, but their conductivity can be greatly increased by adding a small amount of impurity. This process in know as doping for making a semiconductor. Then they can be use to make electronic devices diode, transistors or Integrated Circuits.Two type of semiconductor metrical are obtained depending on various types of impurities. They are like n-type and p-type semiconductors. The n-type semiconductors are doped with silicon (Si) and Phosphorus (P). The p-type semiconductors are doped with silicon (Si) and boron (P). In practical field there are thousand of semiconductors are developed for different uses by different manufacture and it is Hard to Find Semiconductors for right purpose.

The earth is a small plant in the universe. This is the only place in the universe where life ids possible. It is generally believed that the earth is about 46oo million years old. Life appeared in this earth more than 3000 million years ago. The science and technology made t tremendous progresses in the resent century and in the previous century. The natural diversity of the earth made it so special as a living place. The earth atmosphere is consisting of the essential gases like Nitrogen and oxygen. The valued of carbon –di-oxide is very important fro the all plants. The plants made their own food with the help of carbon di oxide. When the life began on the earth some 3100 years ago the earth atmosphere probably contained nitrogen ammonia, hydrogen, carbon di- oxide and carbon – monoxide. Some other valuable gases are hydrogen sulphide, methane but no free oxygen was there in the atmosphere. All the volcanoes were very active at that time. They contributed a large proportion of gases in the atmosphere.

As there was no oxygen there was no Ozone layer. Ozone is formed by the action of shortwave radiation oxygen. The UV ray from the Sun can easily enter into the earth’s atmosphere. This UV light m made a well contribution in the formation of life on the earth. The climate of the earth at that moment was very dangerous. The frequent thunders and electric discharges were common and naturally occurred at that time. Under the influence of energy in the form of UV ray and electric discharge and gases from volcano and variable temperatures some how synthesizes the organic molecule called amino acid which is unit of forming a protein molecule. The important comportment of every living cell is DNA and RNA. They are formed from some inorganic substance. After 3100 million year human being are the superior in the living kingdom. Only human can save this earth… almost one percent of the atmospheric gases are now green house gases. .. Ozone is a minor constituent of atmosphere but play an extremely significant role by providing a protection screen against deadly UV radiation n. thus making life on land possible. The maximum concentration of ozone is around 10 ppm in the stratosphere where it exists as a band at altitude of about 25-30 km. carbon dioxide is a colorless, non-toxic gas that readily dissolves in water.

How’re, since about 1850 the level of CO2 in the atmosphere has been rising dramatically rises. This produces a deep impact on the world climate. The two most important reasons for this increases in carbon di oxide in the atmosphere are estimated that from about 290 ppm in 1850. Now it has increases about 334 ppm in 1979it is going to be double in the next 10 years. The green house gases produce form various sources like automobiles, industries and refrigeration and air conditioning. The CO2 has some unique properties like it can absorbing the outgoing heat in from of infrared radiation. Hence increases in carbon dioxide in the atmosphere would result in a warming of the earth. The warming is popularly referred to as greenhouse effect. It m takes its name from the warming in green houses where sunlight freely enters through the glass panes, but the heat generated in the form of infrared radiation in largely absorbed by the same glass panes. In the other words CO2 acts much as the glass pans do preventing heat to escape. It is the green living style that can reduces the production of green house gases and consequently the heat generation due to green house gases will also reduced. We need more technology that will find energy efficient way to get a green eco-friendly living.

E- Waste means the electronics waste material that produces different chemical substances harmful results for our environment. E-waste has become one of the most power full threats for the world environment.

Mercury Hg, leads Pb are the most powerful harmful substance of e-waste. Laptop and UPS batteries contain this kind of substances that are very awful for Health.

The technology is changing day buy day we are depending of electronic and electrical equipment fro our daily needs. Therefore the numbers of electronic devices are increased 20 – 45 percent I n the recent decades. These electronic junk are not recycled properly and due to less space in we storing these waste in our nearest living places. Risk less management of e-wastes is causing a hazardous for any locality. The scientific solution of e- waste problem is not just collecting all the e-waste and throw that in a lonely place is not a solution. Different organizations are working to develop environment friendly e-waste solution for any institute of offices that refused to use the e-waste. Some organization never want to disposed there e-waste as they contain many important data about their employees – if it is a educational organization than e-waste sometimes contain important data that need s some kind of security, before damaging or recycling those data a storage devices they want proper destruction of these stored data. The e-wasted are recycled in more eco-friendly manners.

ATOMIC SIZE, METALLIC CHARACTER, NON-METALLIC CHARACTER, IONIZATION POTENTIAL,ELECTRON AFFINITY,ELECTRONEGATIVITY& THEIR

some importent topic of chemistry

DEFINITION, EXPLANATION & VARIATION

ATOMIC SIZE -It is the distance between the center of the nucleus of atomo and its outer most shell. It is also called atomic radius. Unit of atomic radii

is A

[Angstrom unit] 1A*=10 to the power –10m. Atomic size depends on 2 factors-

{i} NUMBER OF SHELLS{ii}NUCLEAR CHARGE

NUMBER OF SHELLS-Increase in the number of shells increases atomic size as distance between the outermost shell & nucleus increases.

NUCLEAR CHARGE-Increase in the nuclear charge of an atom decreases atomic size as the electrons in the outer most shell are attracted towards the nucleus with a

greater force.

VARIATION:-IN A GROUP -the size of atom increases as one moves from top to bottom due to successive addition of shells as one moves from one period to the

next.

VARIATION:-IN A PERIOD -the size of atom decreases from left to right as nuclear charge increases.

, METALLIC CHARACTER -The elements which have a tendency to lose their valence electrons and form a positive ion are said to exhibit metallic character. It

depends on atomic size & nuclear charge.

The force of attraction decreases when atomic size increases so elements become more metallic in nature & when nuclear charge increases force exerted by nucleus

increases so elements become less metallic in nature.

VARIATION:- IN A GROUP- metallic character increases as one moves down a group

VARIATION:-IN A PERIOD– metallic character decreases from left to right.

, NON-METALLIC CHARACTER – The elements which have a tendency to gain electrons and form negative ion are said to exhibit non-metallic character. It depends

on atomic size & nuclear charge.

The force of attraction increases when atomic size decreases so elements become more non-metallic in nature & the tendency to gain electrons increases when

nuclear charge increases so elements become more non-metallic in nature.

VARIATION:- IN A GROUP—non-metallic character decreases as one moves down a group

VARIATION:-IN A PERIOD—non-metallic character increases from left to right in a period.

IONIZATION POTENTIAL -It is the amount of energy required to remove the most loosely bound electron from an isolated neutral gaseous atom and convert it into

a positively charged ion. It is measured in volts per atom[eV/atom] & its S.I. unit is kilo joule/mole[kJ/mole]. It depends on 2 factors:- atomic size & nuclear charge

The force of attraction decreases when atomic size increases & the force of attraction increases when nuclear charge increases

VARIATION:- IN A GROUP—Ionization potential decreases as one moves down a group as atomic size increases.

VARIATION:-IN A PERIOD— Ionization potential increases from left to right in a period.as atomic size decreases & nuclear charge increases.

. ELECTRON AFFINITY-The amount of energy released while converting a neutral gaseous atom into a negatively charged ion [anion] is called electron affinity.

It depends on 2 factors:- atomic size & nuclear charge.

If the size of atom decreases electron affinity increases & if nuclear charge increases electron affinity increases.

VARIATION:- IN A GROUP—electron affinity decreases as one moves down a group as atomic size increases than nuclear charge.

VARIATION:-IN A PERIOD— electron affinity increases from left to right in a period.as atomic size decreases & nuclear charge increases..

,ELECTRO NEGATIVITY- It is the tendency of an atom in a molecule to attract the shared electron pair towards itself.

It depends on 2 factors: – atomic size & nuclear charge.

If the size of atom increases electro negativity decreases & if nuclear charge increases electro negativity increases.

VARIATION:- IN A GROUP— electro negativity decreases as one moves down a group as the effect of increase in atomic size is overcomes the effect of increase of

nuclear charge.

VARIATION:-IN A PERIOD— electro negativity increases from left to right in a period as nuclear charge increases due to increase in atomic number.

• MODERN PERIODIC TABLE

  After the discovery of large number of elements they were to group in families showing max resemblance. So the elements were grouped in the form of table in which properties of elements were repeated after regular intervals.

  CLASSIFICATION

• 

  Earlier chemists, scientist arranged elements on the basis of valency, metallic & non-metallic character. Scientists like Dobereiner[1815-1829],Newland[1864],,Mendeleeff[1869] arranged elements in the increasing order of their At.wts. [atomic weights].Moseley[1912] arranged elements in the increasing order of their At. no.[atomic number] in a modified table called Modern Periodic Table[M.P.T].

  Arrangement of elements in the M.P.T. is based on the Modern Periodic Law, which states that –Physical & Chemical properties of elements are based on At. no. & not.At.wt. IMPORTANT FEATURES OF M.P.T. SYSTEMATIC ARRANGEMENT- elements are arranged in increasing order of their At. no. in horizontal rows called “Periods” & vertical columns called “Groups”. PERIODS-M.P.T. has 7 periods. Each period starts with a Alkali metal having 1 electron in it’s outermost shell & ends with 0 group noble gases having completely filled outer shell [8 electrons].

  GROUPS-M.P.T. has 18 groups. Each group has same outermost shell configuration having similar properties.18 groups are-I—VII,VIII & 0.Groups I—VII are subdivided into A & B.

  GROUP-IA-ALKALI METALS- React with water forming strong alkalis-Lithium, Sodium, Potassium, Rubidium, Caesium, Francium.

  GROUP-IB-COINAGE METALS-Used to make coin-Copper,Silver,Gold.

  GROUP-IIA-ALKALINE EARTH METALS-React with water forming strong alkalis-Berilium, Magnesium, Calcium, Strontium, Barium,Radium.

  GROUP-VIIA-HALOGEN GROUP-Found under sea, highly electronegative-Fluorine,Chlorine,Bromine,Iodine.

  GROUP-0-NOBLE GASES-Chemically inert & non-reactive in chemical reactions-Helium, Neon, Argon, Krypton,Xenon,Radon

  [GROUP-IIIB TO GROUP-VIIB-TRANSITIONAL METALS]-Have ‘d’ electrons, Paramagnetic in nature, Colourful

  [GROUP-IA TO GROUP-VIIA-NORMAL ELEMENTS]-Half filled ,consists of metals & non-metals.

Matter and it’s compositionMatter is classified on the basis of physical & chemical properties.

Physical properties being solids liquids gases. Chemical properties –elements ,compounds & mixtures. Physical nature of matter is based on particles of matter. Particles mainly consists of molecules which consists of atoms . rain water contains 10 to the power 21 particles. Many evidences show that matter contain particles. It can be proved by diffusion & Brownian motion .for example if we open a perfume bottle at one corner of the room, It can be smelt in the whole room- it is because of diffusion. if a gas jar containing air is placed upside down on a gas jar of bromine vapour , both gases get equally mixed.

Matter is both rigid & fluid. Rigid-unbending & flexible. Fluid-can flow easily.Matter is mainly classified as physical & chemical. Physical –solids,liquids,gases.Chemical-elements,compounds,mixtures.Solids are classified as amorphous & crystalline.Mixtures are classified as homogenous & heterogenous.Solids have definite shape and volume.Liquids have definite volume but no definite shape.Gases have no definite shape or volume.

Change of state from- solid to liquid is called melting ,liquid to gas is called boiling-brought up by heating.Gas to liquid is called condensation,Liquid to solid is called freezing-brought down by cooling.Solid to gas or gas to solid is called sublimation-by heating or cooling.
