Energy of an electron in hydrogen atom in ground state is –13.6 eV.

1.	Energy of an electron in hydrogen atom in ground state is –13.6 eV. What is the energy of the electron in the third excited state?
Answer» SOLUTION :`E_1 =- 13.6=EV ` ` E_3= ( -13.6 )/( n^2)" where " n=3` `E_3 = ( -13.6 )/(9)= 1.511 eV ` ENERGYOF THEELECTRON in thethirdexcitedstate= 1.511eV .
