The Angular Momentum Quantum Number, l
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The angular momentum quantum number, l, ranges from 0 to n − 1 within a shell, setting the subshell that sets shape.
Show
Within n = 3, l can be 0, 1, or 2, giving the 3s, 3p, and 3d subshells.
Watch for
The values of l depend on n — a shell never has a subshell with l reaching or exceeding n.
