The ground state energy of hydrogen atom is −13.6 eV. What are the kinetic and potential energies of the electron in this state?
Answers
The ground state energy of hydrogen atom is −13.6 eV. The kinetic and potential energies of the electron in this state are -27.2 eV.
Energy is the scalar and not a vector.
The total electric potential energy are mainly associated with the set of charges that would simply adds the energy associated with each of the pair.
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.
