Understand that the principal quantum number, n, defines the energy level of an electron in an atom. For this problem, n = 2.
Recall that the azimuthal quantum number, l, defines the shape of the electron's orbital and can take on integer values from 0 to n-1.
Since n = 2, the possible values for l are 0 and 1, because l can be any integer from 0 up to n-1.
The value l = 0 corresponds to an s orbital, and l = 1 corresponds to a p orbital.
Therefore, for the 2 energy level, the possible values of l are 0 and 1, which correspond to the s and p orbitals, respectively.
