Question

A neutral atom of an element has 2K, 8L, 8M and 2N electrons. The total number of electrons present in the orbitals having $l$ value 1 are :

• A. $6$
• B. $8$
• C. $10$
• D. $12$

Answer 1

The correct option is D $12$

2K , 8L , 9M , 2N
1s 2s 2p 3s 3p 4s $3d^2$
$l=1\Rightarrow porbital$ $total=12electrons$
