• Energy shifts (ΔE_k's) of the principal Kβ peaks of magnesium, aluminium, and silicon existing in the form of binary compounds with second-period nonmetal elements i.e. carbon, nitrogen, oxygen and fluorine, were measured relative to simple substances: Mg, Al, and St. On the basis of the assumptions that (i) the energy of the principal Kβ line can be equal to the energy difference between the 2p (nonmetal) and the 1.5 (metal) orbitals, and that. (ii) this difference in solids can be kept equal to that in free atoms under the condition that no transfer of electrons occurs between the metal and nonmetal atoms, and the change of this energy difference with the transfer of electrons will be proportional to ionicity of the bond, the following equation was derived, E_<2p(nonmetal)> + ΔE_k=E_<3s,3p(metal)> + const.×ionicity. The experimental results agree with this equation.
