The electronic configuration of an element with atomic number 26 is

A

`[Ar]4s^(2)3d^(6)`

B

`[Ar]4s^(1)3d^(5)`

C

`[Ar]3d^(8)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
C
`Na:[Ne]3s^(1)`, unpaired electron=1
`Cl:[Ne]3s^(2)3p^(5)`, unpaired electron =1
`P:[Ne]3s^(2)3p^(3)`,unpaired elecrons =3
`Q:[He]2s^(2)2p^(4),` unpaired electrons =2
