The energy of the electron in the ground...

The energy of the electron in the ground state of hydrogen atom is `-13.6 eV`. Find the kinetic energy and potential energy of electron in this state.

Text Solution

Verified by Experts

As we khow, kinetic energy =-total energy
`=-(-13.6) eV=13.6 eV`
and potential energy =+(total energy )
`=2(-13.6) eV =-27.2 eV`
