3. Curved atoms
Formation of crystals of atoms occurs under the action of the nucleon and electromagnetic forces. Crystallization of atoms of chemical elements occurs on the basis of hydrogen and its isotopes (deuterium, tritium, etc.), so that the crystal atoms have asymmetry as in the weight distribution as in the distribution of electric charges, except carbon, silicon, neon, and helium. In this regard crystals of 1, 3, 5, 6 and 7th groups of the periodic system of elements are electrically asymmetric polar particles.
