4f → n = 4 l = 3 m = -l to + l - 3 to +3

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

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

$n = 3, l = 2, m = - 2, S = + \frac{1}{2}$

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

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

$4 f \to n = 4$
$l = 3$
$m = - l$ to $+ l$
$- 3$ to $+ 3$

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

n=4,l=3,m=+4,s=+21​

n=3,l=2,m=−2,S=+21​

n=4,l=3,m=+1,s=+21​

n=4,l=4,m−4,s=−21​

4f→n=4 l=3 m=−l to +l −3 to +3

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

$n = 3, l = 2, m = - 2, S = + \frac{1}{2}$

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

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

$4 f \to n = 4$
$l = 3$
$m = - l$ to $+ l$
$- 3$ to $+ 3$
