But they have a very high electronegativity.

但它们的电负性非常高。

Which so friction-less because of fluorine's extreme electronegativity.

由于氟的极端电负性， 因此摩擦较小。

An atom's relative greed for electrons is called its electronegativity.

子对于电子的相对贪欲叫做负电性。

And there's a very small difference in electronegativity between the carbon and the hydrogen.

碳和氢之间的电负性差异非常小。

Electronegativity is a little bit more specific.

电负性更具体点。

Let's look at the differences in electronegativity between sodium and chlorine.

让我们看看钠和氯之间的电负性差异。

So this is an overview of electronegativity.

所以这是电负性的概述。

Alcohols and aldehydes have a lot of similar properties because of the electronegativity of the oxygen.

。 由于氧的电负性， 醇和醛具有许多相似的性质。

We care about the relative differences in electronegativity.

我们关心电负性的相对差异。

Well, for this example, each carbon has the same value for electronegativity.

好吧，对于这例子，每碳都具有相同的电负性值。

That's a difference in electronegativity of zero.

这是零电负性的差异。

That, along with the difference in electronegativities of oxygen and hydrogen, leads to the polarity of water and the existence of life.

那， 连同氧和氢的电负性差异，导致了水的极性和命的存在。

Carbon has an electronegativity value of 2.5.

碳的电负性值为 2.5。

So the difference in electronegativity is somewhere between 1.5 and 2.1, between a polar covalent bond and an ionic bond.

所以电负性的差异介于 1.5 和 2.1 之间，介于极性共价键和离子键之间。

Electronegativity increases from left to right because there are more protons in the atoms, and more protons means more boys in the band.

电负性从左到右增加，因为子中有更多的质子，更多的质子意味着乐队中有更多的男孩。

So there is the difference in electronegativity between those two atoms, but it's a very small difference.

所以这两子之间的电负性存在差异，但差异非常小。

Now in extreme cases, like if the electronegativity is greater than 1.6, then we end up with two ions in the same molecule.

现在在极端情况下，比如如果电负性大于 1.6，那么我们最终会在同分子中得到两离子。

And they're so closely related that in general, if something has a high electronegativity, they have a high electron affinity, but what does this mean?

它们之间的关系如此密切，以至于般来说，如果某物具有高电负性，它们就具有高电子亲和力，但这意味着什么？

And this is typical when you're dealing with two elements that aren't very different in terms of their electronegativity or their desire to attract electrons.

当你处理两种电负性或吸引电子的倾向差异不大的元素时，这种情况很常见。

And if your difference in electronegativity is 0.4, that's considered to be a non-polar covalent bond.

如果你的电负性差异是 0. 4，那被认为是非极性共价键。
