Question

what is the value of the azimuthal quantum number (l) for an electron in the 4f orbital?

Explanation:

Step1: Recall azimuthal quantum number rules

The azimuthal quantum number \( l \) has values \( 0,1,2,3,\cdots \) corresponding to \( s,p,d,f,\cdots \) orbitals.

Step2: Match orbital type to \( l \) value

For an \( f \) orbital, the value of \( l = 3 \).
