There are several main branches of chemistry including analytical chemistry, organic chemistry, inorganic chemistry, physical chemistry, biochemistry, nuclear chemistry, and materials chemistry. Analytical chemistry involves the separation, identification, and quantification of chemical components. Organic chemistry is the study of carbon-containing compounds. Inorganic chemistry covers non-organic compounds including minerals, salts, and water. Physical chemistry examines the physical and theoretical properties of chemical systems. Biochemistry studies chemistry in living organisms. Nuclear chemistry deals with radioactive elements and processes. Materials chemistry prepares and analyzes functional substances.
