Abstract

  Usually in the literature metal bond is described as implemented through socialization external electrons of atoms and not possessing the property orientation. Although there are attempts (see below) to explain directed 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 fun

  Abstract. The main problem is that using X-rays, we have determined the crystal lattices of different materials, and why they are so, and not others are not yet known. For example, copper crystallizes in the fcc lattice, and iron in the bcc, which becomes fcc on heating, this is used for heat treatment of steels. Copper does not change the crystal lattice when heated.      There are many factors affecting the crystallization in the literature, so they decided to remove them as much as possible, and the metal model in the article, say so, is ideal, i.e. all atoms are the same (pure metal) without inclusions, without implants, without defects, etc. using the Hall effect and other data on properties, as well as the calculations of Ashcroft and Mermin, my main determining factor for the type of lattice was the core of the atom or ion, which resulted from the transfer of some electrons to the conduction band.     It turned out that the metal bond is due not only to the
