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

由于氟的极端电负， 因此摩擦较小。

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

一个原子对于电子的相对贪欲叫做负电。

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

碳和氢之间的电负差异非常小。

Electronegativity is a little bit more specific.

电负更具体一点。

But they have a very high electronegativity.

但是它们具有非常高的电负。

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

。 由于氧的电负， 醇和醛具有许多相似的质。

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差异。

So this is an overview of electronegativity.

所以这是电负的概述。

We care about the relative differences in electronegativity.

我们关心电负的相对差异。

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

那， 连同氧和氢的电负差异，导致了水的极和命的存在。

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

好吧，对于这个例子，每个碳都具有相同的电负值。

That's a difference in electronegativity of zero.

这是零电负的差异。

Carbon has an electronegativity value of 2.5.

碳的电负值为 2.5。

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

所以电负的差异介于 1.5 和 2.1 之间，介于极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.

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

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，比如如果电负大于 1.6，那么我们最终会在同一个分子中得到两个离子。

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，以至于一般来说，如果某具有高电负，它们就具有高电子亲和力，但这意味着什么？

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

所以这两个原子之间的电负存在差异，但差异非常小。

And so this is just a quick summary of some of the intermolecular forces to show you the application of electronegativity and how important it is.

因此，这只是一些分子间作用力的简要总结，旨在向您展示电负的应用及其重要。

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

如果你的电负差异是 0. 4，那被认为是非极共价键。
