So oxygen gets 3 pairs, and each chlorine gets 3 pairs, so now we're up to 9 pairs.
那么氧都有三对,每个氯有三对,那么现在我们用了九对了。
Well, oxygen, we'll put a hydrogen here, 1 2 3 4 hydrogen here, and one, two, three, four.
如果把一个氢放在这边,另一个氢这边,然后。
So it's going to be a sigma bond, 1s and we have oxygen 2 s p 3 and hydrogen 1 s.
它是sigma键,我们有氧2sp3和氢。
