Elements A,B,C,D and E have following electronic configuration.
(A) `1s^(2),2s^(1) 2p^(1), (B) 1s^(2),2s^(2) 2p^(6) , 3s^(2) 3p^(1)`
(C) `1s^(2),2s^(2)2p^(6),3s^(2) 3p^(3)` (D) `1s^(2),2s^(2)2p^(6),3s^(2) 3p^(5)`
(E) `1s^(2),2s^(2) 2p^(6) , 3s^(2) 3p^(6)`
Which among the belongs to same group in the periodic table. ?
