And they bind using strong, ionic bonds.

而且他们结合使用的是离子级的链接。

So when the researchers cut into strips of their new rubber, the ionic bonds broke.

所以，当研究人员切割新型橡胶时，链接断裂了。

These ionic bonds hold the rubber molecules together and strengthen the material, just like the sulfur bonds did.

这种级别的结合可以把橡胶分子绑定一起，强化材料强度，就像用硫磺固定处理一样。

But, pushing the two pieces together allowed the pairs find each other again and form new ionic bonds.

但是，当把他们拼接到一起时可以再次结合成新的离子链接。

Why is it called an ionic bond?

为什么叫离子键？

So this right here is an ionic bond.

所以这就是离子键。

They're weaker than the forces that cause ionic or covalent bonds between atoms.

它们比引起原子间离子键或共价键的力弱。

And then they stuck to each other, so this is an ionic bond.

然后它们相互粘在一起，所以这是一种离子键。

But the crucial thing about ionic bonds is that they can easily break and reform, just like the snaps on a jacket.

但是对于离子绑定非常关键的是他们容易断裂和重组，就像夹克上的纽扣一样。

And so this force of attraction, this is an ionic bond.

所以这种吸引力，这是一种离子键。

So this represents an ionic bond.

所以这代表离子键。

And so we know this is an ionic bond between these two ions.

所以我们知道这是这两个离子之间的离子键。

So if you're higher than 1.7, it's generally considered to be mostly an ionic bond.

所以如果你高于1.7，它通常被认为主要是离子键。

But sometimes you might want to treat the bond in red as being an ionic bond.

但有时您可能希望将红色键视为离子键。

So we could consider this to be an ionic bond.

所以我们可以认为这是一种离子键。

Or you could treat it like an ionic bond down here.

或者你可以把它当作离子键来对待。

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 和 2.1 之间，介于极性共价键和离子键之间。

And so here, we're treating it like an ionic bond.

所以在这里，我们将其视为离子键。

But you'll see in a few minutes that we could also consider this to be an ionic bond.

但是你会在几分钟后看到我们也可以认为这是一种离子键。

So let's go ahead and draw a picture of carbon and lithium where we're treating it as an ionic bond.

因此，让我们继续绘制碳和锂的图片，我们将其视为离子键。
