- Аннотация: The fourth group of pure diamond-like elements is, in addition to diamond, silicon, germanium, alpha tin, and diamond-like lead. Flerovium (114 Fl) closes this group. There should be no other elements in this group according to the fine structure constant or the Sommerfeld constant α = e2 / ħc. The parameter α is a dimensionless quantity, and its numerical value is close to 1/137. The fine structure constant determines the limit of the maximum number of protons in the nucleus, at which electrons can still have stable orbits. In other words, this constant allows us to determine that with the highest probability, the last neutral atom of the periodic table will be element 137. In the case of diamond-like phases with a sphalerite structure, the limiting value of the heat capacity Ср falls on 114 elements (114Fl) and has 30.5065 J mol-at-1 K-1 = 3.67 R or Ln (Cp/R) = 1.3.
