可以讲到碳原子，是个好消息。

And this is really good news because it's good to get passed carbon.

然而让碳原子一个一个结合通常不是件容易的事。

However, getting one carbon atom to bind to another is often not an easy task.

这可能是由于碳原子的电中性造成的。

This is possible because of the electrical neutrality of the carbon atom.

我们未曾涉及不对称碳原子。

We have made no reference to asymmetric carbon atoms.

看来大部分人都知道碳原子应该在中间。

So most of you saw that carbon should be in the center.

让我们看一下这个碳原子。

So let's take a look at this with carbon.

这样的碳原子称为手性碳。

Such a carbon is designated as a chiral carbon.

每个碳原子的价键为四。

Every carbon atom has four bonds.

这样的碳原子称为手性碳。

Such a carbon is designated as a chiral carbon .

石墨烯由排列成格子状的碳原子组成，看起来像铁丝网。

Graphene consists of carbon atoms held together in a lattice like chicken wire.

youdao

这两个碳原子之间能有吗？，如果我们有一个？

Can we have one between these two carbons here if we have one here?

youdao

糖含有碳原子。

There are carbon atoms in sugar.

其分子同样也应该小，也就是说，该燃料应该含有少量的碳原子。

Its molecules should also be small, that is, they should contain few carbon atoms.

现在利用这件特定的仪器，就可以真正观察到单个碳原子了。

Now with this particular piece of instrumentation, you can actually spot individual carbon atoms.
