The ground state energy of hydrogen atom is -13.6 eV. When its electron is in the first excited state, its excitation energy is
Multiple Choice Options
- A 10.2 eV
- B 0
- C 3.4 eV
- D 6.8 eV
Step-by-Step Verified Solution
E n = _ 13.6 n 2
E 1 = -13.6 eV
E 2 = _ 13.6 2 2 = -3.4 eV
_ _ E = ( � 3.4) � ( � 13.6) = 10.2 eV.
