Answer

(i) The element of group 1 [IA] of period 3 is Na and it’s chloride forms ionic bond and is in solid state.

The element of group 15 [VA] of period 3 is P and it’s chloride forms covalent bond and is in liquid / solid state.

The element of group 16 [VIA] of period 3 is S and it’s chloride forms covalent bond and is in liquid state.

(ii) The element of group 1 [IA] of period 3 is Na and it’s oxide forms electrovalent bond and is strongly basic in character.

The element of group 13 [IIIA] of period 3 is Al and it’s oxide forms electrovalent bond and is amphoteric in character.

The element of group 16 [VIA] of period 3 is S and it’s oxide forms covalent bond and is acidic in character.
