Her design is made up of two long black granite pieces that meet at an angle.

But because there's this lone pair here, it's pushing down on the other bonds, 5° so we end up with an angle of less than 109 . 5 degrees.

但因为这里有孤对，它会把其它键向下压，所以键角会小于109。

self y Notice what I also do here, I create self dot y, give it a value, and then, oh cool, I can also set up what's the radius and angle for this point, by just doing a little bit of work.

我创建了，然后给它赋值，然后，噢太酷了，通过做一点额外的工作,就可以得到点的半径和角度了，好，实际上如果。

So we can have our two hydrogen atoms come in here, and what we will find is - now that we have all of our orbitals filled up -- so thinking about what this angle is here, would you expect it to be less than or greater than what we saw for ammonia before?

我们在这里有两个氢原子，我们会发现,现在我们所有的轨道都填满了-,考虑一下这里的角度，你们觉得它比在氨中看到的,要大还是要小？

they are first graders, but they are kind Harako and like to write to us. I'll show Harako here, Harako and her regular clothes, but I have this little angle that was sitting up here. The kids would say, "what is that, what is that?"

他们都是一年级学生，很友善,很愿意给我们写信，我给你们展示一下，这是Harako和她的日常服装，这还坐着一个小天使,孩子们回问：,“那是什么，那是什么？“

And the second point is of radius 3 and angle 1, which is up about there.

半径为2然后角度为1的一个点,也就是差不多在这儿，我认为为了确保我做的是。
