Which has least I.E. `[3p^(3), 3p^(6) ,2p^(3),2p^(6)]`

Four elements P,Q,R & S have ground state electronic configuration as: {:(P rarr 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(3),Q rarr 1s^(2) 2s^(2)2p^(6)3s^(2)3p^(1)),(R rarr 1s^(2) 2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(3),S rarr 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(2)4p^(1)):} Order of IE_(1) values among the following is

An element has electronic configuration 1s^(2),2p^(6),3s^(2),3p^(3) . Predict their group and block.

Name the dipositive ion represented by configuration : 1s^(2) 2s^(2) 2p^(6)3s^(2)3p^(6) .

simplify: (i) 2p^(3) - 3p^(2) + 4p - 5- 6p^(3) + 2p^(2) - 8p - 2 + 6p + 8 (ii) 2x^(2) - xy + 6x - 4y + 5xy - 4x + 6x^(2) + 3y (iii) x^(4) - 6x^(3) + 2x - 7 + 7x^(3) - x + 5x^(2) + 2 - x^(4)

Consider the electronic configuration of 2 elements: (P) 1s^(2),2s^(2)2p^(6),3s^(2)3p^(3) (Q) 1s^(2),2s^(2)2p^(6),3s^(2)3p^(4) Choose the incorrect option:

Element A, B, C, D and E have the following electronic configurations A: 1s ^(2) 2s ^(2) 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) 4s ^(2) Which among these will belong to the same group in the periodic table ?
