===Basic principles of chemistry===
[[Outline of chemistry|Chemistry]] – branch of science that studies the composition, structure, properties and change of [[matter]].<ref name="definition"/><ref name="Chemistry"/> Chemistry is chiefly concerned with [[atom]]s and [[molecule]]s and their interactions and transformations, for example, the properties of the [[chemical bond]]s formed between atoms to create [[chemical compound]]s. As such, chemistry studies the involvement of [[electron]]s and various forms of [[energy]] in [[photochemical reaction]]s, [[redox|oxidation-reduction reactions]], [[Phase transition|changes in phases of matter]], and [[Separation process|separation of mixtures]]. Preparation and properties of complex substances, such as [[alloy]]s, [[polymer]]s, biological molecules, and [[pharmaceutical]] agents are considered in specialized fields of chemistry.
