Answer :
Quantum numbers are used in chemistry and quantum physics to explain the values of conserved quantities in the dynamics of a quantum system.
Quantum Number of Angular Momentum (l)
The angular momentum quantum number (l) denotes the general shape or area in which an electron exists—its orbital shape. The value of l is determined by the value of n, the fundamental quantum number. Positive values of the angular momentum quantum number range from zero to (n 1).
I hope this helps <3
