In ancient Greece, most people thought that matter was made up of combinations of four elements: earth, air, fire and water.
WebFollowing the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model, since it pictured the atom as a miniature “solar system” with the … WebIn the classical model, the atom is composed of smaller particles with an electrical charge known as electrons and protons. The atom also features a third, neutral kind of particle known as neutrons. Atomic models seek to understand how these particles make up the atom.
