In order to get a good understanding of the human body, it is important to know it at its very basic level: Atoms.

Atoms are the smallest, most basic unit of a chemical element. They are made up of a nucleus, which is made of neutrons (no charge) and protons (positively charged). Nuclei are positively charged. The atomic weight is, of course, determined by the approximate sum of the protons and neutrons inside of an atom.

Atoms also have electrons, which are negatively charged. If the number of electrons is even with the number of protons, the charge of the atom is neutral: An atom. If the atom has more electrons than protons, it is negatively charged and is then known as an anion. (Just think “Nio” sounds like “No!” No is negative.) However, if there are more protons than electrons, the atom is positively charged and known as a cation.

Cations and Anions are both ions. Ions can be loosely defined as any atom that is charged positively or negatively, usually do to the loss or gain of an electronic.
