Given the availability of a force of atomic unification, a sharp interconnection between an antineutrino and a neutron must constitute an antineutrino hydrogen atom. This is one of two atoms that are of crucial value for constructing all of the remaining ones. We discuss a theory in which atomic orbit quantization around a nucleus is carried out with a flavor type dependence. Such an orbit quantized sequence principle leads to the splitting of the spectral lines of atoms in an external field, confirming the availability of a family structure in them. Thereby, it predicts the existence in nature of 63 189 isotope forms of 118 types of atomic systems. We derive the united equations that relate the masses in an atom to the radii of boson, lepton, and antineutrino orbits including the speeds,... energies, and revolution periods of their particles. The estimates thus found express, for each of the five forms of uranium and the two types of hydrogen, the idea of an intraatomic force quantized by leptonic families. They unite all of connections necessary for the steadiness and completeness of an atom in a unified whole as a role of gravity in atomic construction. Therefore, a change in both the lifetime and radius of any of the structural particles within an atom originates from the orbit type dependence.
