Question

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

Answer 1

Ground state energy of hydrogen atom is $E=-13.67eV$

The kinetic energy of the electron is given as:

$KE=-E$

$=+13.67eV$

The potential energy of the electron is given as:

$PE=-2\times KE$

$=-27.2eV$
