Basics of chemistry

What is chemistry? Chemistry is the study of matter, including its composition, properties, and structure; how it changes; and how it interacts with energy.

What is geometry? Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things.

Main Branches of Chemistry

Organic and Inorganic

Since chemistry is such a broad and vast subject, we can divide it up into more manageable topics to help us more accurately. For example, organic and inorganic chemistry divide up all matter into two categories of study. Organic chemistry is the study of the carbon compounds that make up living things. Inorganic chemistry is the study of everything else.

Biochemistry

Biochemistry is the study of the chemical processes that go on in living things and includes the large biological molecules, like DNA, proteins, carbohydrates, and lipids.

Analytical Chemistry

Analytical chemistry is the analysis of chemicals, their properties, and how they react. It also involves the development of tools and methods for doing this analytical work. Analytical chemistry is used by chemists of all disciplines, but some professionals focus solely on the development of analytical methods.

Physical Chemistry

Physical chemistry is the study of physical principles that underlie atoms and compounds, in other words, the physics of chemical compounds. This means that physical chemists examine how particles move, how energy is involved in reactions, the speed at which reactions occur, and how light and energy interact with matter.
