What is azimuthal quentan numbers can exist for n=3?

Answer 1

Azimuthal quantum numbers describe the shape of atomic orbitals and are denoted by the letter l. The allowed values of l are integers ranging from 0 to n-1, where n is the principal quantum number.

For n = 3, the possible values of the azimuthal quantum number l are 0, 1, and 2. These correspond to the orbital shapes of s, p, and d orbitals respectively.

So, for n = 3, the possible azimuthal quantum numbers are l = 0, 1, and 2.
