Energy of Electron Formula
Bohr calculated the energy of an electron in the nth level of the hydrogen atom by considering the electrons in circular, quantized orbits as
where 13.6 eV is the lowest possible energy of a hydrogen electron E(1).
An electron absorbs energy in the form of photons and gets excited to a higher energy level. After jumping to the higher energy level, also called the excited state, the excited electron is less stable, and therefore, would quickly emit a photon to come back to a lower and more stable energy level. The emitted energy is equivalent to the difference in energy between the two energy levels for a specific transition. The energy can be calculated using the following equation
The formula for defining the energy levels of a hydrogen atom is given by
where E0 is 13.6 eV and n is 1,2,3……and so on
