An energy of `24.6 eV` is required to remove one of that electrons from a neutal helium atom. The enegy (in `eV`)required to remove both the electrons from a netural helium atom is

A

38.2

B

49.2

C

51.8

D

79

Text Solution

Verified by Experts

The correct Answer is:
D
After removing one electron from helium atom it will become hydrogen like atom.
`:.E=24.6+(13.6)^(2)=79eV`
