Negative 1 plus 0 should add up to negative 1, if in fact, we're correct for the c n anion.

负一加上零应该等于负一，如果是这样，我们对于氰离子的结果就是正确的。

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 that in the case of constant volume, U in this case that's my delta u, and then I'll H add my little delta n term to get delta H.

这是在等体情形下，此时的到的是Δ,然后我可以加上Δn的项来得到Δ

They're not going to want to add on another electron, because then it'll have to jump a very large energy level go from n equals 2, to n equals 3, and n equals 4, and so on.

它们不愿意增加另外一个电子，因为这会让它们跳到一个非常高的能级上去,依次是，n，等于，2，3，4，等等。
