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。

So we know that we're in the n equals 5 state, so we can find what the binding energy is here.

我们知道,我们在n等于5的态，我们可以找到结合能是多少。

So, we need to find another scheme, and that solution was provided for us by G. N. Lewis.

所以我们需要寻找另一个理论来解释，而G。N。Lewis已经提供了答案。

So, if we just rearrange this equation, what we find is that z effective is equal to n squared times the ionization energy, IE all over the Rydberg constant and the square root of this.

我们可以发现有效的z等于n的平凡，乘以电离能除以里德堡常数,这些所有再开方，所以等于n乘以,除以RH整体的平方根。
