To excite the hydrogen atom from its ground state to second excited state…. eV energy is required.

A

`3.4`

B

`12.09`

C

`1.51`

D

`13.6`

Text Solution

Verified by Experts

The correct Answer is:
B
Knowledge based question
For H-atom, Ground state energy `E_(1) = - 13.6 eV `
`2^(nd)` excited state energy `E_(3) = -3.4 eV`
Energy required to excite from ground state to `2^(nd)` excited state.
`E_(3)-E_(1)=3.4+13.6=+120.9eV`
