我会取一个元素,然后去查看列表,来决定要把那个元素放到哪里,这就意味着它依赖于列表的长度,对,这没什么说服力,但是事实上。

And, one other thing that I failed to point out, if you take a look at the energies associated with the outermost electrons, in this case, lithium, you see it's 0.5 megajoules per mole, and then what's the 6.26?
还有另外一点我忘记提到的是,如果你观察离最外层,的电子的能量,在这种情况,对于锂,你可以得到,它是每摩尔0。5兆焦,那么6。26是什么呢?
And so what I'm going to do the next day is return to this discussion, and take a look at a more rational view of the chemical world. So, we'll see you on Friday.

我选择甲烷这个例子,我们可以看到,如果有一些我们没有考虑到的因素,我们需要修改一下我们的模型,我们看一看,甲烷CH4这个多原子分子,就会知道这一点,甲烷。
