Question

The ground state energy of hydrogen atom is –13.6 eV. What are thekinetic and potential energies of the electron in this state?

Answer 1

Given: The ground state energy of the hydrogen atom is −13.6 eV.

This is the total energy of the hydrogen atom. Kinetic Energy is given as the negative of the total energy. Therefore,

Kinetic Energy=−E =13.6 eV

Potential energy is given by the negative of two times of kinetic energy. Therefore,

Potential Energy=−2×( 13.6 ) =−27.2 eV

Thus, the kinetic energy is 13.6 eV and the potential energy is −27.2 eV.
