The oxygen atom has a slight negative charge while thehydrogen atoms share a compensating positive charge.
氧原子有轻微的负电荷,而氢原子则带对应的正电荷。
That means each of its molecules contains an oxygen atom as well as the carbon and hydrogen found in an alkane.
就是说每个分子也都含有氧原子以及在烷烃中存在的碳和氢。
So in oxygen again, this is just showing the valence electrons, so we end up having six valence electrons from each oxygen atom.
所以在氧里面,这里只展示价电子,我们最后每个氧得到6个价电子。
Hydroxyl is the combination of one hydrogen atom and one oxygen atom.

We could also, I think, well, maybe this isn't written out in terms of that convention, which sometimes it's not, so let's also try writing it, such that we have the hydrogen and the oxygen atom there.
我们也可以,我想,好吧,还有可能它不是按照惯例写的,有时候会出现这样的情况,因此,让我们把氢原子和,氧原子成键的情况也写出来。
So in oxygen again, this is just showing the valence electrons, so we end up having six valence electrons from each oxygen atom.
所以在氧里面,这里只展示价电子,我们最后每个氧得到6个价电子。
