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

由于氟极端电负性， 因此摩擦较小。

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

一个原对于电对贪欲叫做负电性。

And the intermolecular force, in turn, depends on the electronegativity.

而分间力又取决于电负性。

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

让我们看看钠和氯之间电负性差。

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

碳和氢之间电负性差非常小。

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

。 由于氧电负性， 醇和醛具有许多似性质。

But they have a very high electronegativity.

们具有非常高电负性。

And that allows us to compare different elements in terms of their electronegativities.

这使我们能够根据电负性比较不同元素。

So Linus Pauling actually calculated electronegativity values for the elements and put them into the table.

所以 Linus Pauling 实际上计算了元素电负性值并将们放入表中。

For example, we are concerned with carbon, which has an electronegativity value of 2.5.

例如，我们关注碳，电负性值为 2.5。

And we're going to compare that to oxygen, which has an electronegativity value of 3.5.

我们将把与电负性值为 3.5 氧气进行比较。

And to think about, to just think about electronegativity makes it a little bit more tangible.

想想，只要想想电负性就会让变得更加有形。

And especially when you start going into oxidation numbers and things like that, electronegativity will tell you a lot.

特别当你开始研究氧化数之类东西时，电负性会告诉你很多。

I'm going to compare carbon to oxygen in terms of the electronegativity.

我将在电负性方面比较碳和氧。

And then in blue, it gives us the Pauling scale for electronegativity.

然后在蓝色中，为我们提供了电负性鲍林标度。

So that's an electronegativity difference of 1.4.

所以这 1.4 电负性差。

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

那， 连同氧和氢电负性差，导致了水极性和生命存在。

The electronegativity value for carbon we've seen is 2.5.

我们看到碳电负性值为 2.5。

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

所以电负性差介于 1.5 和 2.1 之间，介于极性共价键和离键之间。

And so that's a difference in electronegativity of 1.5.

所以这 1.5 电负性差。
