Abstract: The atomic core model of alkali metal and hydrogen-like atoms is analyzd from physical essence images, polarization and throughout the role of quantitative analysis and experimental data. The semi-experiential internal interaction potential of alkali metal and hydrogen-like atoms is introduced and the stationary Schrodinger equations is established. With perturbation theory obtaining level, the effective main quantum number and effective nuclear change number and its losses are derived further.

Key words: alkali atoms, atoms kernel, polarization and run through, lever
