What is Chemistry
Chemistry is a branch of natural science that deals 
principally with the properties of substances, the 
changes they undergo, and the natural laws that 
describe these changes.
The 5 Branches of Chemistry 
• Inorganic 
• Organic
• Analytical
• Physical
• Biochemistry

Inorganic Chemistry
• The study of chemicals that do not 
contain carbon.
Organic Chemistry
The study of chemicals that contain carbon.
Origin: study of chemicals in living organisms.
Areas of Chemistry
The study of modern chemistry has many branches, but 
can generally be broken down into five main disciplines, or 
areas of study:
Physical chemistry: Physical chemistry is the study of 
macroscopic properties, atomic properties, and 
phenomena in chemical systems. A physical chemist may 
study such things as the rates of chemical reactions, the 
energy transfers that occur in reactions, or the physical 
structure of materials at the molecular level.
Organic chemistry: Organic chemistry is the study of 
chemicals containing carbon with hydrogen. Carbon is 
one of the most abundant elements on Earth and is 
capable of forming a tremendously vast number of 
chemicals (over twenty million so far). Most of the 
chemicals found in all living organisms are based on 
carbon.
Inorganic chemistry: Inorganic chemistry is the study of 
chemicals that do not, in general, contain carbon. 
Inorganic chemicals are commonly found in rocks and 
minerals. One current important area of inorganic 
chemistry deals with the design and properties of 
materials involved in energy and information technology.
Analytical chemistry: Analytical chemistry is the study of 
the composition of matter. It focuses on separating, 
identifying, and quantifying chemicals in samples of 
matter. An analytical chemist may use complex 
instruments to analyze an unknown material in order to 
determine its various components.
Biochemistry: Biochemistry is the study of chemical 
processes that occur in living things. Research may cover 
basic cellular processes up to understanding disease 
states so better treatments can be developed.
  Why Study Chemistry?
it involves math and equations, many people shy away 
from chemistry or are afraid it's too difficult to learn. 
However, understanding basic chemical principles is 
important, even if you don't have to take a chemistry class 
for a grade. Chemistry is at the heart of understanding 
everyday materials and processes. Here are some examples 
of chemistry in daily life:
