It is considered unpromising today to study huge interval between nucleus and atom external shell, so called femtoregion, spread from nanometers to femtometers. But without knowledge of atoms spatial structure and their fields it is impossible to construct molecules correctly, and to build nanoobjects further. Femtotechnologies have to lay down in a theoretical basis of nanotechnologies without which development of applied researches is impossible. In work the femtoregion of the simplyest element, atom of hydrogen, is considered. It is shown that the electron in atom of hydrogen has the difficult spatial structure taking which into account allows to specify fundamental constants, such as a constant of thin structure, the speed of light, Bohr radius of an electron. It is shown that on the basis of these constants it is possible to construct the fundamental scales scaling both internal and external fields of atoms. It allows to formulate macroquantum laws that govern the Universe. It means that without research atoms femtoregion it is impossible to eliminate an abyss which arose between gravitation and electromagnetism. It is shown that our model removes a number of theoretical contradictions and is perfectly confirmed by the last astrophysical experiments.
