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.

一个原子对于电子的相对贪欲叫做负电性。

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

而分子间力又取决于电负性。

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。

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。

But they have a very high electronegativity.

但是它们具有非常高的电负性。

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电负性差异。

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

那， 连同氧和氢的电负性差异，导致了水的极性和生命的存在。
