Bohr model of hydrogen atom explains

Total energy of electron in ${\mathrm{n}}^{\mathrm{th}}$  orbit is proportional to ${\mathrm{n}}^2$ .

Radius of ${\mathrm{n}}^{\mathrm{th}}$  orbit is indirectly proportional to ${\mathrm{n}}^2$ , the angular momentum of electron in an orbit is integral multiple of h /2$\mathrm{\pi }$ and magnitude of potential energy of an electron is greater than its kinetic energy.
