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

例如分子中原子有着联系。

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

它是最完美构，本质上就是碳原子组合。

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

通常情况下，不同分子通过原子间化学相连接。

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

分子内将是氯和氢之间。

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

那是因为它们强度。

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或力量要弱。

That structure is made up of covalent bonds holding that molecule together.

该构由将分子合在一起构成。

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

这是疯狂不稳定。 这基本上就像有一半悬在原子上。

This is a polar covalent bond between the carbon and the oxygen.

这是碳和氧之间极性。

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

它讲是网络固体，这些固体由相互连接原子构成巨大网络组成。

This is within the context of a covalent bond, how much electron affinity is there?

这是在背景下，电子亲和能有多大？

It's Mr. Andersen and this is chemistry essentials video 19 on covalent bonding.

我是安德森先生，这是关于化学基础视频 19。

So somewhere in between there must be the difference between non-polar covalent bond and a polar covalent bond.

所以在两者之间，必定存在非极性和极性区别。

And if so what type of covalent bond is it.

如果是这样, 它是什么类型。

And so if you think about the electrons and the covalent bonds between carbon and oxygen that are shared, they're shared unequally.

所以如果你考虑到碳和氧之间电子以及它们享，这些电子是不均匀享。

Let's think about one of the most famous sets of covalent bonds, and that's what you see in a water molecule.

让我们想想一组最着名，那就是你在水分子中看到。

To turn nasal spray into meth, you’d need to first break its very strong covalent bonds, and that requires dangerous reagents and expensive, high-pressure lab equipment.

要将喷鼻剂变成冰毒， 您需要首先打破其非常牢固，而这需要危险试剂和昂贵高压实验室设备。

Really though, hydrogen bonds aren't chemical bonds in the same sense that ionic and covalent bonds are, but they are the strongest interactions that occur between molecules.

真， 氢并不是像离子和那样化学，但它们是分子之间最强相互作用。

So when we look at a molecule like DNA what we're really seeing are the covalent bonds between all of those atoms that give us this structure.

因此，当我们观察 DNA 这样分子时，我们实际上看到是赋予我们这种构所有原子之间。

It only has one Valence electron that's the electron that could be swiped away from it or that somehow could be involved in a covalent bond somehow.

它只有一个电子，这个电子可能会被移走，或者以某种方式参与形成。
