Interaction of the thermal and crystal constants of the alkaline-earth elements oxides (Ca, Sr, Ba, Ra) and magnesium

Taking the alkaline-earth elements oxides (Mg, Ca, Sr, Ba, Ra) and Mg as a sample the authors show the validity of the mathematical model of estimation of the enthalpy of destruction (formation) of the crystal pattern connection to the reference data. They prove the idea that bounding strength in the connections of this type is determined by coulombian interparticle interactions.
