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

Options

A. n=3, l=0, m=0, s= +1/2
B. n=3, l=1, m=1, s=+1/2
C. n=3, 1=2, m=1, s= + 1/2
D. n=4, l=0, m=0, s= +1/2

Answer

C

Explanation

3d orbital has the highest energy. The increasing order of energy orbitals is :
`3s lt 3p lt 4s lt 3d`
