A spectrum line results from a transition between two energy levels of an atom The frequency of the. energy levels in electron volts, 1 eV being 1.60217733 % 10-19 J. Energy levels of neutral atoms are typically of the order. energy level diagrams is the energy of the atom, and in equation 7.1.4 ∆E is the change in energy of the atom. This includes the kinetic energy of all the particles in the atom.
