The electrons identified by quantum numbers n and l :-
(a) n=4, l=1 (b) n=4, l=0 (c ) n=3, l=2 (d) n=3, l=1
Can be placed in order of increasing energy as

A

AltCltBltD

B

CltDltBltA

C

DltBltCltA

D

BltDltAltC

Text Solution

Verified by Experts

The correct Answer is:
C
Electron with lower value of (n+l) will have less energy: if (n+l) values are same then the orbital with lower value of 'n' will have lesser energy.
