How to use the acid-base character of oxides to classify elements as metals or non-metals?

answer:

the classification of oxides is done into neutral, amphoteric and basic or acidic based on their acid-base characteristics.

an acidic oxide is an oxide which when combined with water gives off an acid.

a basic oxide is an oxide which when combined with water gives off a base.
