The ground state energy ofhydrogen atom is тИТ13.6 eV. What are the kinetic and potential energies of theelectron in this state?



Answer -

Ground state energy of hydrogenatom,┬аE┬а= тИТ 13.6 eV

This isthe total energy of a hydrogen atom. Kinetic energy is equal to the negative ofthe total energy.

Kineticenergy = тИТ┬аE┬а= тИТ (тИТ 13.6) =13.6 eV

Potentialenergy is equal to the negative of two times of kinetic energy.

Potentialenergy┬а=┬атИТ 2 ├Ч (13.6) = тИТ 27 .2eV
