An atom is the subcomponent of a compound, and it is composed of subatomic particles. Every part of baryonic matter above this point, is composed of neutral, ionized, or anionized atoms. They are so small that quantum physics begins taking effect at this point, and properties such as superposition become possible, hence the Tier 1 terminator status of the atom. Current atomic models now use quantum principles to better explain and predict this behavior.
Atoms have a nucleus of protons and neutrons in the inside, and, much further out relatively, an array of electrons orbiting the nucleus. An atom is considered an ion if it has more protons than neutrons and electrons, and anion if it has more electrons then protons and neutrons.
The number of protons in the atom's nucleus, called the atomic number of the atom, provides a way to categorize atoms into 118 elements. For example, an iron atom contains 26 protons. The elements are then divided into isotopes based on the number of neutrons.
Atom is part of a series on verses.
