If the electron configuration of an element is `1s^(2), 2s^(2), 2p^(6), 3s^(2), 3p^(6), 3d^(2), 4s^(2)`, the four electrons involved in chemical bond formation will be

A

`3p^(6)`

B

`3p^(6),4s^(2)`

C

`3p^(6),3d^(2)`

D

`3d^(2),4s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`ns^(2)` and (n-1) d electrons (n=4) are involved in the bond formatin.
