Monovalent Compounds

Definiation: Metal with a single ionic charge.

Examples: - sodium chloride (NaCl)

-magnesium oxide (MgO)

-calcium oxide (CaO)

Multivalent Compounds

Definiation: Metal with more than one possible ionic charge

Example: -Iron(II)chloride (FeCl2) -Iron(III)oxide (Fe2O3) -copper(I)oxide (Cu2O)

Polyatomic Compounds

Definition: -Groups of atoms covalently bonded with a charge

-Ions comprised of more than one atom

-Atoms share electrons

Examples: -calcium sulphate (CaSO4) -sodium hydroxide (NaOH) -potassium nitrate (KNO3)
