WebNote that 1 eV is the kinetic energy acquired by an electron or a proton acted upon by a potential difference of 1 volt. The formula for energy in terms of charge and potential difference is E = QV. So 1 eV = (1.6 x 10^-19 coulombs)x(1 volt) = 1.6 x 10^-19 Joules. Now let's calculate the frequency of the 1 eV photon. E = hf, so f = E/h. WebMay 7, 2006 · The diagram shows some of the energy levels of an electron in a mercury atom. Level Q represents the lowest possible energy level.
