Explain the term 'ligand' in coordination chemistry.

Back

A ligand is a molecule or ion that donates a pair of electrons to a metal ion to form a coordination complex.

Front

What is the role of oxidation states in transition metals?

Back

Oxidation states determine the charge of the metal ion and influence the properties of the compounds formed.
