The method of calculating the atomic radius and positive ionic radius of metal

The quantitative relation between atomic radius, positive ionic radius of metal and atomic structure was studied, and a method for calculating the atomic radius and positive ionic radius of metal was proposed.The calculated results showed that the calculated atomic radius and positive ionic radius of metal were in good agreement with the experiment data, and the absolute deviation was 0.004nm for 63 kinds of metals and 87 kinds of ions.
