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

碳间的电负性差异非常小。

The same thing does for CH4 with its tetrahedron of weakly electronegative hydrogens around a more strongly electronegative carbon.

CH4 也是如此，它的弱电负性四面体围绕着更强电负性的碳。

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。

And then that hydrogen is interacting with another electronegative atom like that.

然后与另一个像这样的电负性原子相互作。

So this is an overview of electronegativity.

所以这是电负性的概述。

But they have a very high electronegativity.

但是它们具有非常高的电负性。

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

。 由于氧的电负性， 醇醛具有许多相似的性质。

We care about the relative differences in electronegativity.

我们关心电负性的相对差异。

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

让我们看看钠氯间的电负性差异。

Due to its negative charge, the oxygen in one molecule is attracted to the positive charge of the hydrogen in another molecule.

由于氧原子的电负性，一个水分子里的氧原子会被另一个水分子里带正电荷的原子吸引。

That's a difference in electronegativity of zero.

这是零电负性的差异。

In summary the electricity is coming, not from the lemon, but from a chemical reaction resulting from the differences in electro-negativity between zinc and copper.

总而言，电就因此产生了，并不是从柠檬中产生的，而是因化反应而产生的，也就是锌铜的电负性间的差异。

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

那， 连同氧的电负性差异，导致了水的极性生命的存在。

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

所以电负性的差异介于 1.5 2.1 间，介于极性共价键离子键间。

And it turns out, it's so much more electronegative that it's no longer going to share electrons with sodium.

事实证明，它的电负性要大得多，以至于它不再与钠共享电子。

So it's important to understand something as simple as oxygen is more electronegative than carbon.

因此，重要的是要了解像氧比碳更具电负性这样简单的东西。

If that's the case, the outer electrons spend enough extra time around the element that's more electronegative that chemists label the molecule polar.

如果是这样的话，外层电子会在电负性更强的元素周围花费足够多的时间， 以至于化家将分子标记为极性。

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性值。

Carbon has an electronegativity value of 2.5.

碳的电负性值为 2.5。

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力的简要总结，旨在向您展示电负性的应及其重要性。
