We call the bonds between these atoms covalent bonds.

我们将这些原子之间的键称作共键。

For example, take molecules, atoms held together by covalent bonds.

例如分子中原子有着共的联系。

Now, remember that in a covalent bond two electrons are shared, usually unequally, between atoms.

那么，通常，在共键里，两个电子在原子之间被不平等共享。

It's the ultimate covalently bonded structure, just a couple of carbon atoms.

它是最完美的共键结构，本质上就是碳原子的组合。

Normally, different molecules are connected by covalent chemical bonds between their atoms.

通常情况下，不同的分子通过原子间的共化学键。

Intramolecular is going to be the covalent bond between the chlorine and the hydrogen.

分子内将是氯和氢之间的共键。

These are materials made of polymers, or chains of molecules, that are assembled together using non-covalent bonds.

它们由聚合物或分子链组成，这些聚合物或分子链用非共键聚集在一起。

SPNs do often contain conventional polymers that are held together by covalent bonds.

SPN通常含有由共键在一起的普通聚合物。

That's because of the strength of their covalent bonds.

那是因为它们共键的强度。

Be careful because we've got covalent attachment, and coordinating to metal sites.

要小心，因为我们有共，并与金属位点协调。

To make those parallel, let's change covalent attachment to covalently attaching.

为了使这些平行，让我们将共更改为共。

This is crazy unstable. It's basically like having half of covalent bond dangling off the atom.

这是疯狂的不稳定。 这基本上就像有一半的共键悬在原子上。

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

它们比导致原子之间形成离子键或共键的力量要弱。

It's on covalent network solids which are solids made of these vast networks of interconnected atoms.

它讲的是共网络固体，这些固体由互的原子构成的巨大网络组成。

And so we'll get to those when we start talking about covalent, ionic and metallic bonding.

所以当我们开始谈论共键、离子键和金属键时, 我们就会谈到这些。

But it's going to have a high melting point because you're going to have these covalent bonds.

但是它将具有较高的熔点，因为你有这些共键。

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键时，我们会发现它们的电负性是不同的。

So by covalently attaching and by coordinating to metal sites.

因此, 通过共和协调金属位点。

So we call this a non-polar covalent bond.

所以我们称其为非极性共键。

This is a non-polar covalent bond, like that.

这是一个非极性共键，就像那样。
