Question

1.
The ionisation energy of hydrogen atom is 13.6 eV, the
ionisation energy of helium atom would be ​

Answer 1

Answer:

54.4 ev is the answers..........

Answer 2

Answer:54.4

Explanation: Hydrogen I.e - 13.6 ev

N for this is I.e =z²/n²×13.6

For Hydrogen 13.6- 1/n²×13.6=1

N=1

For helium i.e- 4/1×13.6= 54.4
