Question

How many electrons can be assigned to orbitals designated by the quantum numbers n = 8, ℓ = 2?

Answer 1

n = Principal Quantum Number , l = Azimuthal Quantum Number

l=2→ the d-subshell

When, n =8, l =2 means d-subshell present here.

The d-subshell can hold total of five orbitals.

The maximum number of electrons = 2×5 = 10 (Answer)
