And the key word for covalent bonds is the idea of being Shared.

而关于共价键最关键的一点就在于共用的概念。

So specifically, today we're going to talk about covalent bonds.

特别地，今天我们要专门讲一讲共价键。

So, that's basically the idea of how we are going to be thinking about covalent bonds.

那么，这就是我们所应该想到的基本思路，在考虑共价键时。

Both ionic and covalent bonds arise from the tendency of atoms to attain this stable configuration of electrons.

离子键和共价键都是由于原子要达到这个稳定电子构型而形成的。

So as we said when we first introduced covalent bonds, it's a sharing of electrons, but it's not always an equal sharing.

当我们刚开始介绍共价键的时候，我们说过电子是被共用的，但是共用却不一定是均等的。
