Give four differences between metals and non-metals with reference to their:

(a) Melting point and boiling point

(b) Conductivity of heat and electricity

(c) Malleability

(d) Solubility in water.

(a) Metals have high melting point and boiling point whereas non-metals have low melting point and boiling point.

(b) Metals are good conductors of heat and electricity but non-metals are bad conductors of heat and electricity.

(c) Metals are mostly malleable while non-metals are not malleable.

(d) Metals are insoluble in water while non-metals can be soluble or insoluble in water.
