The electrons, identified by quantum numbers 'n' and (i) 'n=4, l=1' (ii) 'n=4, l=0' (iii) 'n=3, l=2' (iv) 'n=3, l=1' can be placed in order of increasing energy, from the lowest to the highest as

A

`I lt V lt III lt IV lt II`

B

`I lt V lt III lt II lt IV`

C

`V lt I lt III lt II lt IV`

D

`V lt I lt II lt III lt IV`

Text Solution

Verified by Experts

The correct Answer is:
C
Higher the value of (n+1), higher will be the energy of electron. If value of (n+1) is same for any two or more electrons, the electron with higher value of n, has higher energy. Hence, the correct order of energy is
`V lt I lt III lt II lt IV`
`because (n+1) 6 5 5 5 4`
