covalent bonds

基本解釋

And the key word for covalent bonds is the idea of being shared.
而關于共價鍵最關鍵的一點就在于共用的概念。
So, that's basically the idea of how we are going to be thinking about covalent bonds.
那么，這就是我們所應該想到的基本思路,在考慮共價鍵時。
At this level, basic concepts such as bonding, ionic and covalent bonds are briefly introduced to students.
在這一級，基本概念，如氫鍵，離子和共價鍵簡要介紹給學生。

There's not actually chemical covalent bonds that are formed but it's a non-covalent interaction, usually dominated by hydrogen bonding.
所以配體和受體之間不生成共價鍵,這是一種非共價化合反應,它們通常以氫鍵相聯(lián)

And when we talk about covalent bonds, there's 2 properties that we'll mostly focus on, and that's going to be thinking about the bond strength or the energy by which it stabilized when it bonds.
而當我們討論共價鍵的時候，有兩點特性是我們最關注的，那就是鍵的強度,或者說成鍵之后能量降低了多少。

So as we said when we first introduced covalent bonds, it's a sharing of electrons, but it's not always an equal sharing.
當我們剛開始介紹共價鍵的時候，我們說過電子是被共用的，但是共用卻不一定是均等的。

They performed this trick, as they explain in the journal Langmuir, using a substance called phenyl azido, which readily forms covalent bonds with its neighbours when exposed to ultraviolet light.

a type of chemical bond involving the sharing of electrons between atoms in a molecule, esp the sharing of a pair of electrons by two adjacent atoms
