关于同周期元素原子半径大小比较问题初探河南省焦作１１中许晓春我们通常讲的原子半径是通过晶体分析，根据两个相邻原子的平均核间距离测定的。由于核外电子并没有严格固定的运动轨道，电子云也没有明确的边界，实际上无法精确地测量原子核至最外层电子的平均距离，因此... On the issue of comparing the size of the atomic radii of the same period elements, the problem of the atomic radius is usually determined by crystal analysis based on the average internuclear distances of two adjacent atoms. Since the nuclear electrons do not have a rigid fixed orbit, the electron cloud also has no clear boundary, and it is impossible to accurately measure the average distance from the atomic nucleus to the outermost electrons. Therefore...
