The photon radiated from hydrogen corres...

The photon radiated from hydrogen corresponding to `2^(nd)` line of Lyman series is absorbed by a hydrogen like atom 'X' in `2^(nd)` excited state. As a result the hydrogen like atom 'X' makes a transition to `n^(th)` orbit. Then,

A

`X = He^(+), n = 4`

B

`X = Li^(++), n = 6`

C

`X = He^(+), n = 6`

D

`X = Li^(++), n = +9`

Text Solution

Verified by Experts

The correct Answer is:
D
`13.6[1/1 - 1/9] = 13.6Z^(2)(1/9 - 1/(n^(2)))`
