我们使用electronic configuration的目的就在于,我们可以快速判断电子的分布情况。 我们也可以根据最外层电子数,最快锁定一个原子是否丢失或者获得某些电子,成为离子。 对于电子数比较多的,还有一种简便的写法(condensed configuration),先把前面最靠近你正在写electronic configuration的原子的noble gas写出来,再写出剩下的。
What is the ground-state electron configuration of the potassium ion K+? Octet Rule and Ions: Atoms are most stable when they comply with the octet rule of having eight electrons in their valence shell. If the element forms an ion, they either gain electrons to equal eight or ...
