It also connects to galvanic and voltaic cells, chemical bonds and electronegativity, and lemon batteries.

它还涉及了伽伐尼和伏打、学键和负性，以及柠檬。

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

由于氟的极端负性， 因此摩擦较小。

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

我将从负性的角度比较碳和氧。

If we look at chlorine, 3.16, and hydrogen 2.20, there's a difference between those electronegativities.

如果我们观察氯 3.16 和氢 2.20，它们的负性是有差异的。

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。

Remember looking at this chart and seeing how ionization and electronegativity change.

记住查看这张图表并观察离度和负性如何变。

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

然后用蓝色给出了负性的鲍林标度。

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

。 醇和醛有很多相似的性质， 因为氧的负性。

You could just look at their electronegativity differences on that chart.

您只需在该图表上查看它们的负性差异即可。

When we're looking at nonpolar covalent bonds what we're going to find is that their electronegativities are different.

当我们观察非极性共价键时，我们会发现它们的负性是不同的。

Electronegativity is how much an electron, and it's bad to say this, but wants an electron.

负性是指有多少个子，这样说不好，但是想要一个子。

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

所以莱纳斯·鲍林实际上计算了元素的负性值，并将它们放入表格中。

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

这使我们能够根据负性来比较不同的元素。

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

例如，我们关注碳元素，其负性值为2.5。

And so you can see that fluorine is going to have the highest electronegativity on the periodic table.

所以你可以看到氟在元素周期表上具有最高的负性。

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

我们将把这个与氧元素进行比较，氧元素的负性值为3.5。

If we look at oxygen its electronegativity is 3.44.

如果我们看看氧, 它的负性是3.44。

So Linus Pauling says that electronegativity refers to the power of an atom in a molecule to attract electrons to itself.

所以莱纳斯·鲍林说，负性是指分子中一个原子吸引子的能力。

Well, for this example, each carbon has the same value for electronegativity.

在这个例子中，每个碳的负性值都相同。

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，导致了水的极性和命的存在。
