Which of the following sets of quantum numbers is correct for an electron in 4

Question -

Which of the following sets of quantum numbers is correct for an electron in 4f orbital?

Options:

A .

n = 4, 1 = 3, m = + 1, s = + \frac{1}{2}

B .

n = 4, 1 = 4, m = - 4, s = - \frac{1}{2}

C .

n = 4, 1 = 3, m = + 4, s = + \frac{1}{2}

D .

n = 3, 1 = 2, m = - 2, s = + \frac{1}{2}

Answer: Option A
:
A
The possible quantum numbers for 4f electron are
n=4, l=3, m=-3, -2, -1, 0, 1, 2, 3 and
