Contents

Key Stage 3

Meaning

A Metal Oxide is a basic metal compound made of one or more Metal atoms and Oxygen atoms.

About Metal Oxides

Metal Oxides have a pH greater than 7

Some Metal Oxides are insoluble solids.

Some Metal Oxides dissolve in water to make Metal Hydroxides which are alkalis.

Examples

Group 1 Metal Oxides	Group 2 Metal Oxides	Transition Metal Oxides	Group 3 Metal Oxides
Lithium Oxide: Li2O Sodium Oxide: Na2O Potassium Oxide: K2O Rubidium Oxide: Rb2O Caesium Oxide: Cs2O	Beryllium Oxide: BeO Magnesium Oxide: MgO Calcium Oxide: CaO Strontium Oxide: SrO Barium Oxide: BaO	Chemical Formulae may vary for transition metals. Titanium Oxide: TiO2 Manganese Oxide: MnO Iron Oxide: Fe2O3 Copper Oxide: CuO Zinc Oxide: ZnO	Aluminium Oxide: Al2O3 Gallium Oxide: Ga2O3 Indium Oxide: In2O3
