Question

Find the total number of electrons that can be accommodated in the fourth principal energy level.

• A. $2$
• B. $8$
• C. $18$
• D. $32$
• E. $50$

Answer 1

The correct option is D $32$

The total number of electrons that can be accommodated in the fourth principal energy level is, $2+6+10+14=32$
Here, 2, 6, 10 and 14 corresponds to total number of electrons in s, p, d and f orbitals respectively.
