A molecule is formed when atoms join together by chemical bonds. There are over a hundred different types of atom, called elements. The atoms of a particular element are identical to each other.
Now that we have talked about how atoms are combined to make other substances, let's talk about the particles that make up the atom. Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later.
