"If you have an imbalance, or literally too much nitrogen and too much phosphorous getting into those systems, you can essentially deplete the oxygen in that water.

VOA: standard.2010.08.04

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, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.

比如，在这下面我写的是氮分子2,而这个是氢分子，但我在上面把这些分子的形式改写了，大家可以看到,这是一个氢与氢之间的单键，含一个氮与氮之间的三键。

And, although you think that nitrogen, I mean, it's an inert gas.

尽管你认为那是氮气，我的意思是，它是一种惰性气体。

So this means nitrogen has low electron affinity, it doesn't actually want to gain an electron.

这意味着氮的电子亲和能很低，它实际上并不愿意得到一个电子。

And the reason we can see that by looking at this graph is that we see that nitrogen when it's bonded is in an even lower well than we saw for hydrogen.

原因可以通过观察这幅图发现,我们看到氮在成键之后将处于更低的势阱中,对氢而言。
