Q 12.5 The ground state energy of hydrogen atom is –13.6 eV. What are the kinetic and potential energies of the electron in this state?
The ground state energy E=-13.6 eV.
The kinetic energy= -E=13.6 eV
Also, ground state energy = Kinetic energy+Potential energy
E=K+U
U=E-K
U=-13.6-13.6
U=-27.2 eV
The kinetic and potential energies are 13.6 eV and -27.2 eV respectively.
