In a mixture of `H- He^(+)` gas (`He+ `is singly ionized He atom), `H` atom and `He+` ions are excited to their respective first excited state. Subsequently `H` atoms transfer their total excitation energy to `He+` ions (by collisions) Assume that the bohr model of atom is exactly valid.
The quantum number `n` of the state finally populated in `He^(+)` inos is -

A

`2`

B

`3`

C

`4`

D

`5`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaE_(He)=13.6xx4(1/4-1/n^(2))eV,DeltaE_(He)=DeltaE(H)`
