General Terms
Valence electrons
Electrons in the outermost shell, or energy level of an atom.
Core electrons
Electrons that aren't valence electrons, and don't participate in chemical bonding
Lewis model
A model that represents the bonding between atoms, making them molecules, and their electrons to go along with them.

Anion
An anion is a negatively-charged ion. Its formed when an atom gains electrons, causing it to have an overall negative charge.
Cation
A cation is a positively-charged ion. Its formed when an atom loses one or more electrons, causing it to have an overall positive charge.

Compounds
Ionic compounds
Compounds consisting of ions. Two element compounds are usually ionic when one is a metal and the other is a non-metal.
Covalent compounds
Molecules formed by covalent bonds. Two element compounds are usually covalent when both are non-metal.
