What is chemistry?

Chemistry, the part of science deals with the physical and chemical properties, composition, and structure of matter (substance, element, or atom) and interacts with energy. In this category of studies chemistry, we discuss different types of basic topics related to physical or chemical properties, facts, laws, and structures of atoms made by naturally or artificially occurring matter.
