If 13.6 eV energy is required to 10ise the hydrogen atom, then 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
`E_(n) = (136)/(n^(2))eV`
`therefore Delta E = E_(infty - E_(2) = 0 + (13.6)/(2^(2)) = 3.4 eV`
