چکیده انگلیسی
According to the relationship between gravitational potential and electrostatic potential, and the physical meaning of the contrastive mass-to-electricity (mass per unit electricity) Sr, the authors studied the relationship between ionic radius r and Sr. For the positive ions with same electronic configuration r varied directly with lgSr, and for negative ions with same electronic configuration, the relationship between r and Sr conformed to the mathematical model of Michealis-Menten. With regression analysis, ionic radii of 94 elements, among which there were 108 radii of positive ions and 16 radii of negative ions, could be fitted. The correlation coefficient R and test of significance (F) showed that r was closely related to Sr. The average absolute error of the 102 radii of positive ions was only 0.9 pm with the representative radii of ions; the relative error was 1.1%. This led to a set of good ionic radius values. It is a new path of calculating ionic radius that contains complex ions.
