Question

Which one of the following set of quantum numbers is not possible for 4 p electron?

(a) n = 4, l = 1, m = −1, m_s = +\(\frac 12\)

(b) n = 4, l = 1, m = 0, 1 m_s = +\(\frac 12\)

(c) n = 4, l = 1, m = 2, m_s = +\(\frac 12\)

(d) n = 4, l = 1, m = - 1, m_s = +\(\frac 12\)

Answer 1

Correct option is (c) n = 4, l = 1, m = 2, m_s = +\(\frac 12\)

Numerical value of m can not be greater than l.
