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

Options

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

Answer

C

Explanation

`{:(n=3","l=0" represents 3s orbital , ",n=3","l=1" represents 3p orbital"),(n=3","l=2" represents 3d orbital ,",n=4","l=0" represents 4s orbital"):}`
The order of increasing energy of the orbitals is `3slt3plt4slt3d.`
