Bohr Energy Level Calculator
Find the energy of an electron in a hydrogen energy level, or the photon energy released in a jump between two levels of the atom.
E_n = −13.6 ÷ n² eV
Hydrogen's electron can only sit in fixed energy levels, and the level energy is negative because the electron is bound.
