Electron-electron interactions in atoms

This article examines the effect of the electron-electron (ee-) interaction on the internal state of electronic configurations in atoms and ions. Reconstructions based on the scenario of the atomic synthesis of ion-atomic groups (IAG) of helium, lithium and beryllium based on reference data are proposed. The purpose of the article is to identify and determine the basic patterns of its interactions in the structuring of ion-atomic groups (IAG) of the complete Mendeleev atomic group.
