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

Answer»

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

Solution :`A(3d),B(4d),C(4P),D(5s)`.The SEQUENCE of energies is 3d, 4p, 5s, 4d.
