The ground state energy of hydrogen atom is –13.6 eV. What are the kinetic and potential energies of the electron in this state?
Given: Total energy of the Hydrogen atom = Ground state energy of hydrogen atom is –13.6 eV
Since, the kinetic energy is equal to the negative of the total energy
∴ Kinetic energy of the hydrogen atom = - (-13.6 eV) = 13.6 eV
The potential energy is equal to the twice of the negative of the total energy.
∴ Potential energy of hydrogen atom =-2 × - (-13.6 eV)
Potential energy = -27.2 eV.
