A Hydrogen atom and Li^(++) ion are both...

A Hydrogen atom and `Li^(++) ion` are both in the second excited state . If `l_(H) ` and `l_(Li)` are their respective energies, then

A

`l_(H) gt l_(L I) and |E_(H) | gt |E_(L I)|`

B

`l_(H) = l_(L I) and |E_(H) | lt |E_(L I)|`

C

`l_(H) = l_(L I) and |E_(H) | gt |E_(L I)|`

D

`l_(H) = l_(L I) and |E_(H) | lt |E_(L I)|`

Text Solution

Verified by Experts

The correct Answer is:
B
`L = (n h)/(2 pi), |E| prop Z^(2)//n^(2) : n = 3`
`implies L_(H) = L_(Li) and |E_(H)| lt |E_(LI)|`

In a container a mixture is prepared by mixing of three samples of hydrogen helium ion (He^(+)) and lithium ion (Li^(2+)). In sample , all the hydrogen atoms are in 1st excited state and all the He^(+) ions are in third excited state and all the Li^(2+)) ions are in fifth excited state.
