Question

A H-atom and a Li++ ion are both in the second excited state.If l and l' are their respective electronic angular momenta and E and E' their respective energies ,then
1) l>l' and |E|>|E'|
2)l=l' and |E|<|E'|
3)l=l' and |E|>|E'|
4)l<l' and |E|<|E'|
​

Answer 1

Answer:

Given Z  

H

​  

=1,Z  

Li

​  

=3 and n  

H

​  

=n  

Li

​  

=3

1. Angular momentum is independent of Z, therefore l  

H

​  

=l  

Li

​  

 

2. Energy is directly proportional to square of atomic number, hence E  

H

​  

<E  

Li
