🤓 Based on our data, we think this question is relevant for Professor Chen's class at CSULB.
We’re being asked to determine the number of orbitals contained in the third principal level (n = 3).
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: –l to +l.
How many orbitals are contained in the third principal level (n=3) of a given atom?
