Angular Momentum Quantum #

[Lauren Bui 1E]

Where does the angular momentum quantum number come from?

[Mashkinadze_1D]

The orbital angular momentum quantum number corresponds to the subshell. For example, the s is zero, p is one, d is two, and f is three. These are representations of how the electrons are behaving around the nucleus in the electron field.

The angular momentum quantum number is used to describe the 'shape' of the orbital whether l= 0 (s), 1 (p), 2 (d), or 3 (f).

The angular momentum quantum number (l) describes the "shape" of the orbital that an e- occupies. The lowest possible value it can have is 0 and the highest value it can have depends on the principal quantum number, n-1.
For example, an s-orbital is associated with an l=1, p-orbital with l=1, d-orbital with l=2, f-orbital with l=3.
Each l is called a subshell also.
