The non-biodegradable industrial chemicals are attracted to the surface of the iron shavings, where they react by sharing electrons with the iron and become degraded.

非生物可降解的工业化学物质被吸附到铁粉的薄层上面来，与铁膜上的电子反应而降解。

So as we said when we first introduced covalent bonds, it's a sharing of electrons, but it's not always an equal sharing.

当我们刚开始介绍共价键的时候，我们说过电子是被共用的，但是共用却不一定是均等的。

youdao

And he actually proposed sharing - unequal sharing of electrons.

他也确实研究了-，不等性共用电子。

youdao

Well, if this bond has completely identically equal sharing of electrons, then this bond will be nonpolar.

如果一根键连的两个原子,对键上的电子吸引程度是完全等价的，那么这根键是非极性的。

And we can do the same thing with, well, we're going to do it with nitrogen in a minute, but this is a case where we have two atoms sharing electrons.

然后同样的，我们也可以很快的对氮气进行类似的处理，但是这是共用电子,的双原子例子。

I heard some people say one, and that's a good guess, remember they're actually sharing. So these two electrons, they belong to chlorine, they also belong to hydrogen, but they do, in fact, belong to chlorine as well.

我听到有些人说的是一个，这是个很好的猜测，但要记得它们其实是被共用的，因此有两个电子，它们属于氯，同时也属于氢，但实际上它们也属于氯。
