The electronic configuration for some neutral atoms are given below :
(i) `1s^(2),2s^(2),2p^(6),3s^(2)` (ii) `1s^(2),2s^(2)2p^(6),3s^(1)`
(iii) `1s^(2),2s^(2)2p^(6),3s^(2)3p^(2)` (iv) `1s^(2),2s^(2)2p^(6),3s^(2)3p^(3)`
Which of these is expected to have the highest second ionization enthalpy ?

A

(i)

B

(ii)

C

(iii)

D

(iv)

Text Solution

Verified by Experts

The correct Answer is:
B
B atom after losing outermost electron acquires noble gas configration (stable configuration). It is difficult to remove the next electron from `B^(+) (1s^(2),2s^(2)2p^(6))` ion.
