Abstract

  Usually in the literature metal bond is described as implemented through socializationexternal electrons of atoms and not possessing the propertyorientation. Although there are attempts (see below) to explaindirected metal bond as the elements crystallize into a certain type of lattice.In the work\"Nature of chemical elements"\It was shown that the metallic bond in the densest packages (HEK and HCC)between a centrally chosen atom and its neighbors in the general case,presumably, is carried out by means of 9 (nine) directed links, in contrast to the number of neighbors equal to 12 (twelve) (coordination number). Probably \ "strange \" three (3) atoms are present in the coordination number 12 stereometrically, and not because of the connection.The answer should be an experimental test.

  These theoretical studies of the metallic bond in pure homogeneous metals led me to the fact that changes in the crystal lattices of lithium and beryllium as a function of temperature turned out to be approximately the same as for scandium and titanium, respectively, and we had to think about the correctness of the table of elements.
