Chemistry is the study of matter, its properties, how and why combinations of substances or other substances to form them, and how substances interact with energy. Many people think of chemists as white-coated scientists mixing strange liquids in a laboratory, but the truth is that we are all chemists.
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
