Look first at the sheet that gives you the titles of God, and you'll see that in the patriarchal traditions so we're talking about Genesis primarily; I've thrown in some other texts also, but focusing for a moment on the patriarchal traditions of Genesis El SHaddai God is six times called El Shaddai.

you can see that the subcortical here, so this is a brain that was cut away here, here, and here was a chunk taking out, you can see deep into this area you can also see that's what happening in the cortex.

So, if you look at all of these, we have full octets for all of them, and if we count up all of the valence electrons, it's going to be equal to our number 26 here.

So, let's go back to the notes, and let's fill these in, seven electrons. Another way you could have known them was to look at Lewis' notes here, where if look at this box carefully you see there are seven dots around the cube, so there are his seven valence electrons.
那么，让我们回到讲义，把它们填进去，七个电子，还有另外一种方法可以知道这些,那就是看看路易斯的讲义这里，大家可以看到这个立方体周围有七个点,因此有七个价电子。

If we look at our last structure here where we have nitrogen the middle, we can also figure out all those formal charges, and in this case we have plus 1 on the nitrogen, we have minus 2 on the carbon, and then we end up with a 0 on the sulfur there.
如果我们来看看最后一个结构,在中间的原子是氮，我们同样可以计算出所有的形式电荷，而在这种情况下，氮为正一，碳为负二，而最后硫为零。

Now, again, we go through these faster then you can write, and as you all know, the lecture notes are posted on the website, so if you need to go back and refresh your memory on these things you can.
现在我们再快速的过一遍以便大家记录,而且你们都知道,课堂笔记都挂在网上,所以如果你们需要温习,加强记忆,你们可以看看笔记

Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.
通常一开始把电离能最低的原子,放在中心位置就很好了，如果你发现电荷没有分开,那么这个结构就没问题了，但是如果你发现有很多分开的电荷，比如这种情况，有负二，正二和负一，那么你会想要说等一下，从形式电荷来看这很不好，让我去看看其它可能的选择。
-
So I'm going to go over here, and I'm going to type test search-- I can type and if you look at your handout, it's just a sequence of tests that I'm going to do OK. So initially, I'm going to set up the list to be the first million integers.
大家可以看看你们的课堂材料，那儿有一些我要做的实验,好，一开始我先去建立个，含有一百万个integer的数组,对，这有点儿简单,但是这给我提供了这样一个有序的数组。
