《化学通报》1983年第3期刊出“对使用价层电子对互斥模型的一个改进”(以下简称“改进”)一文,介绍了A.F.Wells的8n+2m规则,不必写出AX_n型分子或离子的Lewis电子结构,只需计算形成分子或离子的所有原子的价层电子总数,就可直接确定电子对的空间排 The 3rd Bulletin of Chemical Processing, 1983, entitled “An Improvement to the Use of Electron Pair Mutual Exclusion Models” (“Improvement”), introduces the 8n + 2m rule of AFWells without having to write out AX_n-type molecules or The Lewis electron structure of ions can be directly determined by determining the total number of valence electrons of all the atoms forming the molecule or ion
