Absorbance

Ligand

A small ion or compound that acts as a Lewis base, donating 2 electrons to form a bond with the metal cation

Coordination Complex

Product of the reaction of a metal cation and a ligand

Complex Ion

An ion that contains one or more ligands that are attached to a central metal cation through a dative covalent bond

Bidentate/Chelating Ligand

Lewis bases that donate two pairs of electrons to a metal atom

Chelate

Ligand that makes more than one bond with a metal cation
