Chemistry is chiefly concerned with atoms and molecules and their interaction and transformations. For example the properties of the chemical form between atoms to create chemical compounds. As such, chemistry studies the involvements of electrons and various form of energy in photochemical reactions, changes in phases of matter, and separation of mixtures. Preparation and properties of complex substances, such as alloys, biological molecules, and pharmaceuticals agents, are considered in specialized fields of chemistry. Chemistry is sometimes called the central science because it bridges other natural science like PHYSICS, GEOLOGY and BIOLOGY. Chemistry is a branch of physical science but distinct from physics. The etymology of the word chemistry has been much disputed.
