An electron will have highest energy with which one of the followng sets of four quantum numbers?

Options

A. `{:(n" "l" "m" "s),(3" "2" "1" "+1/2):}`
B. `{:(n" "l" "m" "s),(4" "2" "-1" "+1/2):}`
C. `{:(n" "l" "m" "s),(4" "2" "0" "-1/2):}`
D. `{:(n" "l" "m" "s),(5" "0" "0" "-1/2):}`

Answer

B

Explanation

`A(3d),B(4d),C(4p),D(5s)`.The sequence of energies is 3d, 4p, 5s, 4d.
