   A combination of quantum, classical and additional conditions are utilized to get analytical expression for calculation of ionization potentials of the periodic system elements with accuracy less than 2%. The main admissions made while the interactions model and the expression constructing were: inverse dependence of electron - nucleus distance from element number and proton - electron charge inequality. The model and calculations lead to the conclusion about a tie-up of the line a2 of characteristic X-rays spectrum K-series with ionization potential of the second electron.
