1.	The ground state energy of the hydrogen atom is -13.6eV. What are the kinetic and potential energies of the electron in this state?
Answer» The potential energy (E_p) of the electron in an orbit is equal to twice its total energy (E) = -13.6 x 2 = -27.2eV The kinetic energy (E_k) of the electron in an orbit is equal to negative of its total energy (E) ∴ E_k – E = – (-13.6) = 13.6 eV.
