What is chemistry?

hemistry is the study of matter and the interactions among different types of matter.  Matter is anything that has mass and occupies space.  The first step in learning more about chemistry is to read as much as you  can on your areas of interest.  The book "Chemistry - The Easy Way" is an example of a "very low cost - almost free" guide to get you started.  However, you can study chemistry at this web site totally free. You do not have to purchase anything. Use the menu chart above and start by studying ATOMS, and ELEMENTS. Then take a look at BASIC CHEMISTRY and follow it as an outline for studying the other subjects in the top menu table above. Go through all the topics in the menu table above, one at a time. Above all make it fun and interesting for yourself.  Take your time, don't rush.

Chemistry has four major areas of interest and many sub-specialties.
1.  Organic Chemistry - The study of the element carbon and its compounds including living matter.
2.  Inorganic chemistry - The study of all other elements of non-living matter.
3.  Analytical chemistry - The study of " What is it?" or qualitative chemistry and "How much is there?"  which is quantitative chemistry.  Analytical chemistry is the analysis of compounds. 
4.  Physical Chemistry - The quantitative aspects of the physical properties of substances and their relationship to chemical structure and composition.
- - - - A few sub-specialties in chemistry are:
Biochemistry - The study of biologically active substances.
Polymer chemistry - The chemistry of long chained molecules.

Solid state chemistry - The behavior of solids.
Organometallic chemistry - The chemistry of compounds in which a metal is bonded in an organic compound.
