ionic valence

According to family and group of the elementary ionic law table, one drawing is made with ionic radius as ordinate and outer shell electron distribution as abscissas; and another drawing is made with logarithm of ionic radius as ordinate and valences of ionic as abscissas.

依据元素离子律表的组和族,以离子半径为纵坐标,外层电子排布为横坐标作图;以离子半径的数值为纵坐标与离子价数为横坐标作图,得到两套规律性好的曲线。
