The ground state energy of hydrogen atom is -13.6 eV The potential energy of the electron in this state is
- A 27.2 eV
- B -27.2 eV
- C -13.6 eV
- D 13.6 eV
Answer & Solution
Correct Answer
(B) -27.2 eV
Step-by-step Solution
Detailed explanation
For hydrogen atom, \(\mathrm{E}_{\mathrm{n}}=-13.6 \mathrm{eV}\) \(\therefore \quad P . E=2 E_n=2 \times(-13.6)=-2.72 \mathrm{eV}\)
