Electronic configuration of four element...

Electronic configuration of four elements is given below.Which of the following does not belong to the same group?

A

`[Xe] 4f^(14), 5d^(10),6s^(2)`

B

`[Kr] 4d^(10), 5s^(2)`

C

`[Ne] 3s^(2),3p^(5)`

D

`[Ar] 3d^(10),4s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
In a family, all elements have same outermost electronic configuration. Since `[Ne]3s^(2)3p^(5)`, chlorine belongs to halogen family while the remaining three are in same group i.e. group 12. `""_(80)Hg = [Xe]4f^(14) 5d^(10)6s^(2)`
`""_(48)Cd = [Kr]4d^(10) 5s^(2)`
`""_(30)Zn = [Ar]3d^(10)4s^(2)`
