Problem: Which of the following indicates an orbital in the third energy level?a) 3sb) 5fc) 4dd) 2p

FREE Expert Solution

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 are the range of –l to +l.
