Basic Chemistry

Existence of molecules in nature  molecules exist in the two ways....  1: Homoatomic molecules :  molecules are made up of similar atoms.  2: Heteroatomic molecules :  Molecules are made of the dissimilar atom.  Note: while you writing a chemical reaction you always remember that the atoms always write in its molecular form except inert atom.. OK.......  Now whose atoms exist in molecular formula especially homoatomic molecules which gives a correct a chemical reaction.. Homoatomic molecules :   types* Monoatomic molecules :  He,  Ne,  Ar, kr, Xn, Rn. Diatomic molecules:   H-H -------> H2 ( Hydrogen molecule) N-N --------> N2( Nitrogen molecule) O-O ---------> O2( oxygen molecule) F-F  ---------> F2 ( fluorine molecule)  Cl- Cl --------> Cl2 Chlorine molecule) Br-Br ---------> Br2  I - I  -----------> I2 Triatomic molecules:  Three similar atom  Only one example .... O3 (O...

 Chemical classification of matter.. Let's start I ask you a question ???  Both Your books and  pen are solid but they are same in nature?????   you say..  no ! both both are different in nature because my books is made up of Woods material and and my pen is made up of plastic still they are both but they made up of different kinds of material.... and this is done by knowing their different kinds of material is deal  by internal view or internal nature of material which they  differ to one substance to another substance is chemical classification of matter. Chemical classification               Chemically matter is classified into two categories:  1:  homeogenous matter called pure substances.  2: heterogeneous matter called impure substances. 1: Homogenous matter Homogenous matter means any substance made up of a single kinds of material which are evenly distributed throughout the substa...

Classification of matter :       Dear.... On the basis of external and internal behaviour of matter it divide into two category. 1: physical classification 2: chemical classification 1: physical classification:  Physical classification of matter its mean what is the external view of matter. You are see in your home the table, your books, your pens, computer glass and plates is it tough and this tough called solid.  You also see that in your home when you bath drinking water drinking milk that's matter tendency to flow so it is called liquid. And and you also notice when your mother making a special food you can easily detect that today is special foods making by your mummy. And another case when u  stick a mosquito coil their smell is sprayed  everywhere.this smell is gas Definition of solid liquid and gases..      Solid:     1:  solid has definite mass. 2:  solid has  definite volume.(why?)  3:...

After classification of universe Universe has a two form matter and radiation according to Einstein matter and radiation are related to each other by the using the equation E = mc2 Both are related to each other for example if we take a Chalk and when your teacher write on a blackboard the chalks particles are a down the floor can you see this chalk particles your answer is yes so so this any tiny particle if we see then This particle is is exist in the form of matter but if we this t i n y particle is further broken down with a special instrument and about hundred times smaller then before one and this stage if we can see that particle then we also called matter but again further broken down with special instrument about 1000 times before one and this stage what happened are you see that particle ???? Answer is no!!!!! Where goes the matter??? Answer is the matter is converted into the radiation which has no mass no Volume and cannot be feel our five sense organ (you are confused in t...

Basic chemistry for beginners . Hello dear.... today start the chemistry but before touch your chemistry textbook first we discussed about their terms because if any terms in chemistry is doubtful for you we cannot learn its concept because every pages of chemistry testbook some fundamental terms always found in your line and if any concept or terms is missing by you we are difficult to to understand the chemistry and their concept. so we are startup clear all doubt Let's start  Chemistry start from zero level... . First we start classification of university where chemistry is start......  Basic chemistry for beginners...                             Universe
