Question

identify the elements which will form basic oxide,from the given list-carbon,magnesium,

sulphur,aluminium,

nitrogen,potassium.

Answer 1

Metals usually form basic oxides, while non metals usually form acidic oxides.

Among the given list below, carbon, magnesium, sulphur, aluminium, nitrogen, potassium, Carbon, sulphur, nitrogen are non-metals, hence they form acidic oxides. While,

Magnesium, Potassium are metals, hence they form basic oxides. But Aluminium even though a metal is amphoteric in nature hence forms amphoteric oxide (aluminium oxide Al2O3) which shows both acidic and basic properties.
