Question

Which of the following sets of quantum numbers represents the highest energy of an atom?

A

$n = 4, l = 0, m = 0, s = + \frac{1}{2}$

B

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

C

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

D

$n = 4, l = 0, m = 0, s = - \frac{1}{2}$

Answer

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

Explanation

Solution

For highest energy level in an atom, $(n+ l)$ should be maximum.
