1.	the photon radiated from hydrogen corresponding to the second line of Lyman series is absorbed by a hydrogen like atom X in the second excited state. Then, the hydrogen-like atom X makes a transition of nth orbit.A. `X=He^(+),n=4`B. `X=Li^(++),n=6`C. `X=He^(+),n=6`D. `X=Li^(++),n=9`
Answer» Correct Answer - D Energy of` n_(th)` state in hydrogen is same as energy of `3n^(th)` state in `Li^(++)`.therefore3to1 transaction I H would give same energy as the `9to3` transaction in `li^(++)`.
