(i) Formation of ions.
Metals form cations whereas non-metals form anions.
(ii) Action with dilute acids.
Metals react with dilute mineral acid to liberate hydrogen.
Non-metals do not react with dilute mineral acids.
(iii) Action with hydrogen.
Metals do not react with hydrogen but non-metals react with hydrogen to form hydrides.
