The discovered regularities are explained by the configurationally model of the electronic structure of matter as follows: in subgroups IIIa – VIIIa of groups of the periodic table in the series Ti → Ni, the orbital of d - electrons form, together with the of s-electrons orbital, hybrid orbital, the degree of intersection of which increases with an increase in the ordinal number of elements and, accordingly, the interatomic force of interaction increases. In the copper subgroup, the bond strength is largely provided by s - electrons. A decrease in the energy stability of s - electrons in the transition from Cu (copper) to gold due to an increase in the distance of s - electrons from the nucleus and the degree of screening of the nuclear charge by internal electrons leads to a decrease in the interatomic force of interaction. In metals of the zinc subgroup d10 - the valence electrons in the condensed state is violated due to the excitation of s2 - configurations with the formation of a high concentration of ant bonding unlocalized electrons, the degree of loosening of which increases with an increase in the ordinal number of the element in this subgroup. This leads to a weakening of the force of interaction of atoms with an increase in the principal quantum number of s-electrons.
