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

由于氟的极端电性， 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电性。

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

而分子间力又取决于电性。

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

让我们看看钠和氯之间的电性差。

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

碳和氢之间的电性差非常小。

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

。 由于氧的电性， 醇和醛具有许多相似的性质。

But they have a very high electronegativity.

但是它们具有非常高的电性。

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

这使我们能够根据电性比较不同的元素。

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

所以 Linus Pauling 实际上计算了元素的电性值并将它们放入表中。

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

例如，我们关注的是碳，它的电性值为 2.5。

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

我们将把它与电性值为 3.5 的氧气进行比较。

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

想想，只要想想电性就会让它变得更加有形。

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

特别是当你开始研究氧化数之类的东西时，电性会告诉你很多。

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

我将在电性方面比较碳和氧。

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

然后在蓝色中，它为我们提供了电性的鲍林标度。

So that's an electronegativity difference of 1.4.

所以这是 1.4 的电性差。

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

那， 连同氧和氢的电性差，导致了水的极性和命的存在。

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

我们看到的碳的电性值为 2.5。

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

所以电性的差介于 1.5 和 2.1 之间，介于极性共价键和离子键之间。

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

所以这是 1.5 的电性差。
