The ground state energy of hydrogen atom is -13.6 eV The potential energy of the electron in this state is

The ground state energy of hydrogen atom is -13.6 eV The potential energy of the electron in this state is
  1. 27.2 eV
  2. -27.2 eV
  3. -13.6 eV
  4. 13.6 eV

Solution

For hydrogen atom, $\mathrm{E}_{\mathrm{n}}=-13.6 \mathrm{eV}$ $\therefore \quad P . E=2 E_n=2 \times(-13.6)=-2.72 \mathrm{eV}$
