Abstract

The word “atom” derives from the Greek word “atomos,” which means indivisible; an atom was the smallest indivisible component of matter according to some philosophers in Ancient Greece [1]. However, we now know that atoms are actually composed of subatomic particles: protons and neutrons in the nucleus of the atom, and electrons orbiting that nucleus (Fig. 1.1).
