Atomic Structure Question 314

Question: Which of the following sets of quantum numbers is correct for an electron in $ 4f $ orbital [AIEEE 2004]

Options:

A) $ n=4,,l=3,,m=+1,,s=+\frac{1}{2} $

B) $ n=4,,l=4,,m=-4,,s=-\frac{1}{2} $

C) $ n=4,,l=3,,m=+4,,s=+\frac{1}{2} $

D) $ n=3,,l=2,,m=-2,,s=+\frac{1}{2} $

Show Answer

Answer:

Correct Answer: A

Solution:

For 4f orbital electron, $ n=4 $

$ l=3 $ (Because 0, 1, 2, 3) s, p, d, f m = + 3, + 2, +1, 0, - 1, - 2, - 3 s = +1/2
