Valence Number of bonds (see bonding) an atom can form.
元素的一个原子能够结合其它原子的数目。
Backing that is sealed to the fabric by heat. See Bonding.
通过加热而封密封在织物里面的衬背。见胶粘。
The essential feature of monomer molecules is the ability to form chemical bonds (see bonding) with at least two other monomer molecules (polyfunctionality).
单体分子的基本特性是至少能与两个其它单体分子形成化学键的能力(多功能性)。
You can see that there is no value in studying inner shell electrons to ask questions about bonding.
你应该了解考虑成键时，去考虑内层电子，是毫无意义的。
We see three bonding pairs so this is a triple bond, indeed a multiple bond.
我们看到3对成键电子所以这是一个三重键，它确实是多重键。
So let's see, we started with 8 bonding electrons, and we used up only 4, so the answer is yes, we have 4 bonding electrons left.
那么让我们来看看，我们一开始有八个成键电子，然后只用掉了四个，因此答案应该是还有剩余，我们还剩下了四个成键电子。
PROFESSOR: And I didn't write up there but it is one, 1 and we can see that it's 1, 2 because it's 1/2 of 2, 4 minus 2, so 1/2 of 2, the bonding order is going to be equal to one.
教授：我没有写出来，但是是1，我们可以看到为什么是，因为它等于1/2的2，4减去，所以1/2的2，键序等于1。
So any time you see a star that means an anti-bonding orbital.
任何时候你看到有个星，这意味着它是反键轨道。
That's what we see are involved in bonding.
那也是我们所看到的结合的电子。
They see it as bonding and being supportive.
她们把这看成是增进感情，是情感支持。
In the control group we see improvement, and that was purely because of the social interaction and bonding that occurred.
在对照组中，我们看到的改善，纯粹是因为社会交往和亲密关系的原因。
So you can see that polar covalency is a tendency towards ionic bonding.
所以你看得出极性共价就是，趋向离子键的。
so you can see that there is going to be two sets in antibonding, three sets in bonding for a net of one, giving us the single bond.
因此你能看到,反键轨道上有两组，三组成键，得到一组净成键，所以成的是单键。
PROFESSOR: Two. OK, good. So again, we're going to see that we have a bonding order of 0.
两个，OK，很好，同样的，我们会看到键序是0。
Infant dependency in humans may have lead to the common pattern that we see in humans of pair-bonding.
婴儿依赖大人可能导致了我们人类的一夫一妻关系。
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a means of bonding.
男人把电话看作一种向他人传递各种事实和信息的交流工具，而女人则把它视为联络感情的手段。
So again, this is an anti-bonding orbital, and what you see is that there is now less electron density between the two nuclei than there was when you had non-bonding.
同样的，这是反键轨道，你们看到当你有反键轨道的时候，两个原子核中间的电子密度更小了。
So you can see that this is non-bonding, this is even worse than non-bonding, it's anti-bonding, because we're actually getting rid of electron density between the two nuclei.
所以你可以看到这是不成键的，它甚至比不成键还糟糕，它是反键，因为我们实际上是去掉了，两个原子核之间的电子。
So you can see that this is non-bonding, this is even worse than non-bonding, it's anti-bonding, because we're actually getting rid of electron density between the two nuclei.
所以你可以看到这是不成键的，它甚至比不成键还糟糕，它是反键，因为我们实际上是去掉了，两个原子核之间的电子。
