The ground state energy of hydrogen atom is −13.6eV-13.6 \mathrm{eV}. What is the potential energy of the electron in this state?

Options

  1. A0eV0 \mathrm{eV}
  2. B−27.2eV-27.2 \mathrm{eV}
  3. C1eV1 \mathrm{eV}
  4. D2eV2 \mathrm{eV}.

Correct answer

B. −27.2eV-27.2 \mathrm{eV}

Step-by-step solution

Total energy = kinetic energy + potential energy Potential energy =2=2 total energy =-2 ×\times13.6=-27.2 eV. \mathrm{eV} \text{. }
