Differences in Chemical Properties :-

1 All metals react with oxygen to form metal oxides All non-metals react with oxygen to form acidic or neutral oxides.

2 Metals react with water to produce metal oxide (or metal hydroxide) and hydrogen gas. Non-metals do not react with water.

3 Metals react with a dilute acid to form a metal salt and hydrogen gas. Non-metals do not react with dilute acids .

4 All metals react with chlorine to form ionic metal chlorides. Non-metals react with chlorine to form covalent chlorides.

5 Only a few metals like Na, K, Ca and Mg react with hydrogen to form metal hydrides. Non-metals react with hydrogen to form covalent Hydrides.
