In hydrogen atom, when electron jupms from second to first orbit, then enrgy emitted is

A

`-13.6 eV`

B

`-27. 2eV`

C

`-6.8 eV`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
`E_(n_(1) rarr n_(2)) = - 13.6 [(1)/(n_(2)^(2)) - (1)/(n_(1)^(2))] , n_(1) = 2` and `n_(2) = 1`
`rArr E_(II) rarr E_(1) = - 13.6 xx (3)/(4) = - 10.2 eV`
