Answer:
n = 2
l = 1 (and l can only be 1 for p orbitals)
ml = −1, 0, 1
Explanation:
In the 2p subshell, n = 2 (as it's in the second principal energy level). The l (azimuthal quantum number) values for the p subshell can be l = 1 because p orbitals have l values ranging from −l to +l, and in this case, l = 1.
The ml (magnetic quantum number) values for l = 1 (p orbitals) range from −l to +l, so for l = 1, m l can be -1, 0, or 1. Hence, the possible values for ml in the 2p subshell are -1, 0, and 1.
