Oxides of metals and non-metals may be,
Acidic-exhibits acidic character
Basic-exhibits basic character
Amphoteric-exhibits both acidic and basic character
Neutral-does not exhibit any of the acidic or basic character
Except Beryllium oxide ( ), all the oxides of alkali metals and alkaline earth metal are basic in nature.
None of the oxides of non-metals show basic property.
Oxides of non-metals with higher oxidation number of the main group elements are highly acidic whereas those with lesser oxidation number does not exhibit measurable acidic properties.
Beryllium oxide ( ) and many of the metallic oxides of Group 3A and 4A are amphoteric
