Chemistry from Egyptian kēme (chem), meaning "earth" is the science conce
ed with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.
Chemistry is the scientific study of interaction of chemical substances that are constituted of atoms or the subatomic particles: protons, electrons and neutrons. Atoms combine to produce molecules or crystals. Chemistry is often called "the central science" because it connects the other natural sciences such as astronomy, physics, material science, biology, and geology.
