The paper discusses the revealed regularities in physical change of atomic nuclei located near the proton drip-line and beyond it. Beyond this drip-line,relatively long-lived nuclei in their main energy state can be located. Proton decay ofsuch nuclides does not correlate with a significant spin change, and their half-life can last up to 1 second or more. The common notion of reducing both a half-life period and an average binding energy of nucleus bonds, while the distance is increasing from the stable nucleus line (to an accuracy of the parity or magic number of protons and neutrons) to the congestion of protons or neutrons, can be considered as a special case of a more general dependence. Near the drip-line, this dependence is not a monotonic function, as it is commonly believed, but it more resembles damped oscillations, which do not correlate with either the pairing effect or nuclear shell occupations, or high-energy excitation, or with a large nuclear spin and "helium anomalies". The effect is manifested itself in nuclei that are heavier than magnesium.
