An electron has orbital angular momentum $12 ℏ$ and its orbital has 3 radial nodes. Find $n \times (number of orbitals in that subshell)$ .

Numerical answer type, tolerance 0.01.

Answer: 49

l (l + 1) = 12

gives

l = 3

.

n = 3 + 3 + 1 = 7

. The f subshell has 7 orbitals. Product

= 7 \times 7 = 49

.
