You'll notice that a lot of different kinds medications do you have chlorine in them, you'll see that c l group.
你会注意到很多不同类型的药物都含有氯,你会看到这类氯。
It's like they spell colour, c-o-l-o-r, we spell it c-o-l-o-u-r,
这就像他们拼写颜色这个单词,c-o-l-o-r,而我们拼写成c-o-l-o-u-r,
"That never,ever had a possibility of happening in my experience at U.C.L.A.

So chlorine, if we talk about it in terms of electron affinity, we would be writing that we're actually gaining an electron here, and getting the ion, c l minus.
那么,氯,如果我们要讨论它的电子亲和能,我们会假设它真的得到了,一个电子而变成离子,负一价的氯。
It was a short way of writing a different spelling of the words all correct. Some foreign-born people wrote all correct as o-l-l k-o-r-r-e-c-t, and used the letters O.K.

This is Pieter Claesz, C-L-A-E-S-Z, probably mispronounced.
这是彼得·格莱兹的作品,C-L-A-E-S-Z,我可能发音不准确
D.C.United won the first two M.L.S.championships.

And we give different names, depending on what kind of electrons we're dealing with, so, for example, with h c l here, we can talk about having bonded versus lone pair electrons.
我们还起了不同的名字,给我们要处理的不同类型的电子,以氯化氢为例,我们来介绍一下成键电子与孤对电子。
So, we can put our sulfur in the middle, and then it doesn't really matter how we draw the rest of it, where we put our c l's versus where we put our oxygen.
那么,我们可以把硫放在中间,然后把其它的原子画在哪里就不重要了,把两个氯原子与一个氧原子放在哪里都行。
So, in other words, this c l minus is actually lower in energy than the reactants were.
也就是说,负一价氯离子,比原来的反应物的能量更低。
So, in terms of the c l atom, we need to talk about each atom individually.
对于氯原子,我们需要分开讨论这两个原子。
How many bonding electrons does c l have? All right. Let's see, we've got a mixed response here, it turns out it has two bonding electrons.
氯有多少成键电子?好,让我们来看看,大家的回答不太一致,结果应该是两个成键电子。
And the last example that we're going to talk about is thionyl chloride, so it's s o c l 2. This is another good step forward, because now we actually have four different atoms in our molecule.
我们要讨论的最后一个例子,是氯化亚砜,就是硫,氧,氯,二,这又是一个进步,因为我们的分子中现在有四个不同的原子了。
So I show that here, so in green, you have what's called a carboxcylic acid group, a c o o h, which gets converted by s o c l 2 to a c double bond o c l or an acid chloride.
我在这里用绿色表示,我们所说的羧酸族化合物,碳,氧,氧,氢,它被亚硫酰氯转化为,一个碳氧双键与碳氯单键组成的酰氯。
This is the structure of Lunesta, and you see the c l in it as well.
这是鲁尼斯塔的结构图,大家可以看到这里也有氯。
