(a)Name two physical properties each of sodium and carbon in which their behaviour is not as expected from their classification as metal and non-metal respectively. (b)Name two metals whose melting points are so low that they melt when held in the hand.

Solution:

(a) Sodium is a soft metal with a low melting point.

Carbon is a non-metallic element. Graphite is a carbon allotrope that has a high melting point and is a good conductor of electricity.

(b) Gallium and caesium have a low melting point and will melt in your hand if you hold them.
