Cation

A positively charged ion, often a metal atom that has lost electrons.

Anion

A negatively charged ion, often a non-metal atom that has gained electrons.

Organic Compounds

Compounds made up of carbon, hydrogen, nitrogen, and oxygen atoms, often forming long chains and complex structures.

Inorganic Compounds

Compounds that are not organic, meaning they don't contain long chains of carbon, hydrogen, nitrogen, and oxygen. They can have a wide variety of elements and structures.
