So, as you go down a given group, you're becoming less, less electronegative, electronegative.

所以，当你进入一个给定的群体时，你的负电性会越来越小，负电性会越来越小。

Well, oxygen atoms are more electronegative than hydrogen.

好吧，氧原子比氢原子更具负电性。

The same thing does for CH4 with its tetrahedron of weakly electronegative hydrogens around a more strongly electronegative carbon.

CH4 也是如此，它的弱电负性氢四面体围绕着更强电负性的碳。

Fluorine as we could guess from its spot on the periodic table, love electrons. It is extremely electronegative.

我们可以从它在元素周期表上的位置猜到氟喜欢电子。 它具有极强的负电性。

So what, what are, based on this, what are going to be the most electronegative of all the atoms?

那么， 基于此，所有原子中电负性最强的是什么？

Well, oxygen atoms are more electronegative than hydrogen. The oxygen atom pulls harder on the molecule's electrons than the hydrogen does.

好吧，氧原子比氢原子更具负电性。氧原子比氢原子更能吸引分子的电子。

And so the three electronegative elements that you should remember for hydrogen bonding are fluorine, oxygen, and nitrogen.

因此，对于氢键，您应该记住的三种负电性元素是氟、氧和氮。

But in this situation, oxygen is more electronegative than hydrogen.

但在这种情况下，氧比氢更具负电性。

And we know that because oxygen is more electronegative, and we'll talk about the trends in a second.

我们知道这是因为氧气的电负性更强，我们稍后会讨论趋势。

So oxygen is more electronegative than carbon.

所以氧气比碳更具负电性。
