Which of the following sets of quantum numbers is not possible for a 4p electron?
A
n = 4, l = 1, m = 0, s = +1/2
B
n = 4, l = 1, m = 0, s = −1/2
C
n = 4, l = 1, m = −2, s = +1/2
D
n = 4, l = 1, m = +1, s = +1/2
Correct Answer
Option C
Detailed Explanation
In the option n = 4, l = 1 represents 4p but m = −2 is not possible as the values of m for 4p must vary between −1 to +1.
