###### FREE Expert Solution

We’re being asked to determine the number of orbitals for n = 4 and l = 2.

Recall that the quantum numbers that define an electron are:

• Principal Quantum Number (n): deals with the size and energy of the atomic orbital

The possible values for n are 1 to ∞.

• Angular Momentum Quantum Number (l): deals with the shape of the atomic orbital

The possible values for l are 0 to (n – 1).

• Magnetic Quantum Number (ml): deals with the orientation of the atomic orbital in 3D space.

The possible values for ml is the range of l: –l to +l. ###### Problem Details
