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。

If you were paying attention, you learned that a molecule needs to have both charge asymmetry and geometric asymmetry to be non-polar, that charge asymmetry is caused by a difference in electronegativities, and that I am totally team polar.

如果你注意听了，你应该知道一个分子需要同时具备对称性和几何对称性才能是非极性分子， 对称性是由负性的差异引起的， 且我完全站在极性分子这边。

Inside the quartz is a crystal lattice of one silicon for every two oxygen atoms, which forms a network of covalent bonds, with electrons being more attracted to the oxygen due to their electronegativity.

石英部是由每个硅原子对应两个氧原子组成的晶格，形成了一个共价键网络，由于氧的负性更强， 子更倾向于被氧吸引。

And this is typical when you're dealing with two elements that aren't very different in terms of their electronegativity or their desire to attract electrons.

这在处理两种负性或吸引子的能力相差大的元素时是很典型的。

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。

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 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。

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

它还涉及了伽伐尼池和伏打池、键和负性，以及柠檬池。

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。

The electronegativities of various elements are all super well known, and waiting for you in tables on the internet.

各种元素的负性早已广为人知，你可以在网上的表格中找到它们。

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，这样说好，但是想要一个子。

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。

Now if the electronegativity is different, then we call that a polar covalent bond.

现在, 如果负性同, 那么我们称之为极性共价键。

Just looking at this Carboxylic Acid thing, if you think about the electronegativity of those two oxygens, you can imagine that that hydrogen there is gonna be pretty weakly held.

看看这个羧酸，如果你考虑这两个氧的负性， 你可以想象那里的氢会很弱。

When we looked up the values, we saw that carbon had an electronegativity value of 2.5 and oxygen had a value of 3.5, for difference of 1.

当我们查阅这些数值时，发现碳的负性值为2.5，氧的负性值为3.5，差值为1。

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

由于氟的极端负性， 因此摩擦较小。

So for polarity to occur in a molecule, you have to have two different elements at a minimum, and the difference between their electronegativities has to be 0.5 or greater.

所以要使分子中出现极性，至少需要两种同的元素， 并且它们之间的负性差异必须达到0.5或更大。

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.

这只是一个快速总结，介绍一些分子间作用力，展示负性的应用及其重要性。
