Question

If maximum value of l = 2, then the number of maximum possible electrons in the orbit will be _________.

• A. $2$
• B. $8$
• C. $18$
• D. $32$

Answer 1

The correct option is C $18$

The number of possible orbitals with (l=2) = d with 5 orbitals.

now numbers of orbitals in orbit will be 9 (One S , three p, five d),

Each orbital hold maximum two electrons.

So number of electrons in this orbital is 18.
