If 13.6 eV energy is required to ionize the hydrogen atom

• Matter & Atoms

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

1. 0 eV
2. 3.4 eV
3. 6.8 eV
4. 10.2 eV

Answer

Energy required to remove electron from n^th orbit is

E = - 13.6/n²

The correct option is B.
