In their 1916 papers, both G. N. Lewis and W. Kossel pointed to the electron configurations of these elements as especially stable.

在1916年的论文中，G·N·刘易斯(G . N . Lewis)和W·科塞尔(w . Kossel)都指出，这些原子的电子构型非常稳定。

So, if we took the case of nitrogen, if we add an electron to nitrogen and go to n minus, we find that the change in energy is 7 kilojoules per mole.

如果我们以氮为例，如果我们给氮增加个电子令它变成-1价的氮，我们会发现能量的变化是，7，千焦每摩尔。

And, in fact, it can't even reach n, because then we would have no potential energy at all in our electron, which is not correct.

事实上，它连n都达不到，因为如果那样的话，电子就没有势能了，这是不可能的。

We know that the orbitals for multi-electron atoms depend both on n and on l.

我们知道对于多电子原子轨道,是依赖于n和l的。
