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

由于氟的极端负性， 因此摩擦较小。

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

一个原子对于子的相对贪欲叫做负性。

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

而分子间决于负性。

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

碳和氢之间的负性差异非常小。

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

。 由于氧的负性， 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负性。

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

，只要负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，负性会告诉你很多。

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

让我们看看钠和氯之间的负性差异。

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

那， 连同氧和氢的负性差异，导致了水的极性和生命的存在。

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

这使我们能够根据负性比较不同的元素。

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负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.

我们将把它与负性值为 3.5 的氧气进行比较。

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

负性从左到右增加，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。

So this trend right here, when you go from the left to the right, your electronegativity, let me write this, your getting more electronegative.

所以这个趋势就在这里，当你从左到右时，你的负性，让我写下这个，你的负性越来越强。

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，比如如果负性大于 1.6，那么我们最终会在同一个分子中得到两个离子。

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

我将在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，它为我们提供了负性的鲍林标度。

So that's an electronegativity difference of 1.4.

所以这是 1.4 的负性差异。
