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

Options

  1. A0 eV
  2. B-27.2 eV
  3. C1 eV
  4. D2 eV .

Correct answer

B. -27.2 eV

Step-by-step solution

Total energy = kinetic energy + potential energy Potential energy =2 total energy =-2 13.6=-27.2 eV .
