Bohr's model of hydrogen - Khan Academy
WEBBohr explained the hydrogen spectrum in terms of electrons absorbing and emitting photons to change energy levels, where the photon energy is. h ν = Δ E = (1 n l o w 2 − 1 n h i g h 2) ⋅ 13.6 eV. Bohr's model does not work for systems with more than one electron.
