Химия – наука о веществах, их свойствах, строении и превращениях, происходящих в результате химических реакций. Поскольку все вещества состоят из атомов, которые благодаря химическим связям способны формировать молекулы, то химия, в основном, изучает взаимодействия между атомами и молекулами. Химия подразделяется на неорганическую, органическую, физическую, аналитическую, коллоидную химию, агрохимию, геохимию, кристаллохимию, радиохимию, биохимию, плазмохимию и др. Химия имеет много общего с физикой и биологией. Химия охватывает разные отрасли промышленности: металлургию, нефтехимическую и пищевую промышленность, фармацевтику и медицину.
