A near total system of the average ionic crystallo-graphic radius and their usage for ionization potentials determination

Abstract

It has been suggested a new method of determination of the elements ionic radii in unusual valence. It has been obtained a double-parametric equation from empirical dependance of electron density of element atom in known of atom radius. This equation connects ionic radii of IV-VII periods elements of Mendeleyev Periodical system in two valent states. This allows to calculate ion radius which mustnt be determined with X-ray method because of absence of the stable compounds in this valent state. There have been calculated ionic radii for all elements of IV-VII periods in all valent states. It has been constructed a near total system of ion radii dependance of square root out of ionzation potentials from inverse ionic radii. There have been estimated the ionization potentials of 78 elements experimentally undetermined up to now.
