A hydrogen atom at the grotund level absorbs a photon and is excited to level. The potential energy of the electron in the excited state is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Energy of hydrogen atom at ground state is -13.6 eV. The relation between the principle quantum number and the energy is given by, E=-13.6n2⇒E=-13.616=-0.85 eV Potential energy of an electron in an orbit is twice that of the total energy. Therefore,…
