A phenomenon that modern nuclear physics does not even try to explain is explained. It is shown that the increased composition of the lightest and heaviest elements in the earth's crust is explained precisely by the fact that they cannot participate in reactions with the jump of nucleons between two identical nuclei. When nucleons jump from one nucleus to another, the number of nucleons in one nucleus increases, and in the other decreases. This is impossible for nuclei with the smallest and largest number of nucleons. Such nuclei can no longer participate in such reactions, so their accumulation occurs.
