What Is Chemistry??
Many People are now a days having Problems In learning Chemistry. When It Comes, The First Thing Which Come in Mind Is What is Chemistry???"Chemistry is the branch of Science which deals with the study of composition of matter characteristics of matter and chemical reactions involved in matter."
What is Chemistry Importance in our Life??
In every field of our life Chemistry is used i.e In field of medicine In field of Agricultural industry i.e Cement Industry , Paper Industry, Glass Industry, In Preparation of Paints,Varnishes and Synthetic Fibers, Plastics,Soap and Detergents. We can say that Chemistry is involved in every field of our life.Chemistry also help us to search for new Natural resources.
Let's discuss The Branches of Chemistry First
What is Chemistry Branches??
The Chemistry is divided into following Branches
1. Organic Chemistry is the branch of chemistry which deals with study of compounds containing carbon and hydrogen ie. hydrocarbons.
On Number Two We have Inorganic Chemistry which is branch of chemistry That deals with study of compounds other than hydrocarbons.
3rd One is Biochemistry It is the branch of Chemistry which deals with study of bio molecules like carbohydrates,proteins etc formed in living organisms.
On Number 4 we have Analytical Chemistry that deals with study of complete analysis of chemical compounds.
Number Five is about Physical Chemistry that deals with study of composition of matter and relation between physical properties of matter.
On Sixth number we have Environmental Chemistry that deals with the study of components of Environment and effects of human activities on environment.
Another Branch of Chemistry is Nuclear Chemistry That deals with study of nucler reactions and nuclear properties.
And the last One is about Industrial Chemistry that deals with the study of Preparation of compounds on industrial scale.
Now Lets have Some look on What Chemistry Actuly have in it.
The Chemistry has many things in it Like What is Chemistry Structure of Atom??
Structure of Atom is very important in study of chemistry an Atom is the smallest particle of matter which can take part in a chemical reaction, An Atom can exist independently or Can not Exist Independently i.e He (Helium) and Ne (Neon) can exist independently and atoms like Hydrogen (H2) can not exist independently.
When we study the structure of atom we realize that an atom consists of subatomic particles which are called protons electrons and neutrons.the nucleus is central part of atom protons and neutrons are present in nucleus and electrons revolve in specific paths called orbits around nucleus. Another Thing in Chemistry is Atom's Atomic Numbers Let's have a look at
What is Chemistry Atom's Atomic Numbers?
The number of protons present in nucleus is known as atomic number and the number of protons and neutrons are collectively called mass number it is also called nucleon number because both protons and nutrons are called nucleons.
What is Chemistry Molecules?
Molecules are formed by the combination of atoms.The Question is still there what actully molecule is??
" A molecule is the smallest particle of matter which can exist freely ie.H2."
Chemistry elements can make matter at present. Almost 118 elements are discovered which are consisted of 92 natural and 26 artificial elements.
Another thing in Chemistry is Compounds That are formed by the combination of elements in specific proportion ie "H2O" is molecular formula of water in which O2 and H2 has specific proportion between them.
Here Comes The Other Thing about Chemistry Mixture Which is formed by the combination of elements in any proportion i.e soil is mixture of silica & stones etc.
What is Chemistry Chemical formula??
It is another important step in basics of chemistry it is used to show compounds with help of symbols the molecular formula has two types molecular formula and empirical formula.The molecular formula shows actual number of atoms present in a compound ie glucose has molecular formula C6H12O6 the empirical formula shows the simplest whole number ratio between atoms present in a compound ie glucose has empirical formula CH2O.
Other Basic Thing which is important in Chemistry Chemical Equation that is used to show the chemical reactions with help of formulas and by separating reactants from products with help of an arrow.
