If `13.6 eV` energy is required to ionized the hydrogen atom then the energy required to ionize the hydrogen atom , then the energy required to remove an electron from `n = 2 ` is

A

`10.2 eV`

B

`0 eV`

C

`3.4 eV`

D

`6.8 eV`

Text Solution

Verified by Experts

The correct Answer is:
C
Energy required to lonize a atom from `n^(th)` orbit is
`= +13.6/n^(2) eV`
`E_(2)=(+13.6)/2^(2) eV= +3.4 eV`
