List in tabular from three chemical properties on the basis of which we can differentiate between a metal and a non-metal.

Answer 1

	Metals	Non-Metals
1.	Metals react with oxygen to produce basic oxides.	Non-metals react with oxygen to produce acidic or neutral oxides.
2.	Metals react with water to produce metal hydroxide and hydrogen gas.	Non-metals do not react with water to produce hydrogen gas.
3.	Generally, metals do not combine with hydrogen except sodium, potassium, calcium, and magnesium which form ionic hydrides on reacting with hydrogen	Non-metals react with hydrogen to form covalent hydrides.
