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

$\begin{array}{1 1}(a)\;n=3,l=1,m=1,s=\large\frac{1}{2}\\(b)\;n=3,l=2,m=1,s=\large\frac{1}{2}\\(c)\;n=4,l=0,m=0,s=\large\frac{1}{2}\\(d)\;n=3,l=0,m=0,s=\large\frac{1}{2}\end{array}$

$n=3,l=2,m=1,s=\large\frac{1}{2}$
Because it has the maximum value of n+l
Hence (b) is the correct answer.
