I have shown that by taking Avogadro's number of individual ion pairs and putting them all together in a line, the system's energy became more negative.

我推导出了,从每一个离子对中抽出阿伏加德罗常数,再把它们放在一起在一列中，这个系统的能量就变得更负。

If I can prove that it is greater than one that means that the line is more stable than the set of ion pairs.

如果我可以证明它大于,这就表明,这一line要比这一系列离子更稳定。
