View Solution

On removing an electron the Helium atom becomes a single electron atom, applying Bohr's Model ,the energy of the single electron is given by

-13.6

z 2

n 2

(where z is atomic no. and n is the no. of the shell in which the electron resides).

Thus ,

the energy comes out to be

-13.6

4

1

, which is -54.4.

So ,

the total energy required to remove both the electrons will be

24.6+54.4=79.0
