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.
