Understand that the principal quantum number, n, defines the energy level of an electron in an atom. For the 2 energy level, n = 2.
Recall that the azimuthal quantum number, l, defines the shape of the electron's orbital and can take integer values from 0 to n-1.
For n = 2, calculate the possible values of l. Since l ranges from 0 to n-1, substitute n = 2 into the formula to find the range of l.
Determine the possible values of l for n = 2. The values are 0 and 1, as l can be 0, 1, ..., n-1.
Conclude that for the 2 energy level, the possible values of l are 0 and 1, corresponding to the s and p orbitals, respectively.
