Find out the group of the element having the electronic configuration, `1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6)3d^(6)4s^(2)`.

Text Solution

Verified by Experts

The correct Answer is:
As last electron enters in `d-`subshell, therefore this belongs to d-block. For d-block element the group number is equal to the number of valence sheel electrons + number of electron in (`n-1)` d-subshell. So, group number `= 6 +2 = 8`.
