State :
(i) the bonding and state of chlorides of period-3 — group 1 [IA], 15[VA], 16 [VIA] and
(ii) the bonding and character of oxides of period-3 — group 1 [IA], 13[IIIA] and 16[VIA].
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.
