So again you can see as we're filling up our molecular orbitals, we're using the exact same principle we used to fill up atomic orbitals.
当我们填充轨道的时候可以看到,我们用的是和,填充原子轨道一样的原则。
So we have a total of 2, 4, 6, 8, 10 valence electrons, so I'll make sure I count to 10 as we fill up our molecular orbitals here.
我们一共有2,4,6,8,10个价电子,所以我一边填一边要确认,我数到10。

走出你自己,让这些,奇遇,这些联系填充你的身体,来提升今日的你。
I've got two states here, three states here, two here, I need four, and if I can come up with these bonds, four, by the Hund rule I'd fill them like this.
我们已经有2个状态在这里,3个在这里,2个在这里,我需要4个,如果我能想到这些键,四个,通过洪特规则,我们就能像这样排布。
I want to back up now because I think it's important to fill in a little bit of the historical context behind that long but important prose treatise.
我想要退回去往前看是因为我认为,补充一些历史背景对于,解读那篇冗长却又很关键的政论是很重要的。
He always kept his poise to the top branches, climbing carefully with the same pains you use to fill a cup up to the brim, and even above the brim.
他始终稳住身子,不摇不晃地,直到那高高的顶枝上----小心翼翼地,往上爬,那全神贯注的样儿,就像,把一杯水倒满,满到了杯口,甚至满过了边缘。
You can see that as you fill up your periodic table, it's very clear. But also we'll tell you a pneumonic device to keep that in mind, so you always remember and get the orbital energy straight.
在你们填周期表的时候,非常清楚但是我们也要告诉你们,一个策略去记住它,所以你们总是记得,并得到连续的轨道能量。
So, in order to fill up our shell, what we need is 3 times 8 or 24 electrons.
因此,为了填满所有的壳层,我们需要三乘以八也就是二十四个电子。
They realized that the rice could fill up the entire world with a thick layer.
他们发现米粒,能厚厚地覆盖全世界。
We have to fill up all the gaps.
我们试图打破沉默。
And now we get the p orbitals, remember we want to fill up 1 orbital at a time before we double up, so we'll put one in the 2 p x, then one in the 2 p z, and then one in the 2 p y.
我们到了p轨道,记住在双倍填充之前,我们想要每次填充至一个轨道,所以我们在2px填充一个然后2pz填充一个,然后2py填充一个。
And all we need to do is go over here now and fill up our octets.
而我们所需要做的就是到这里来,把我们的“八隅体“都填满。
Our step three is to figure out how many bonding electrons that we need, or excuse me, how many total electrons that we need to fill up our octets, so that's just going to be 4 times 8, which is 32.
我们的第三步是判断,我们需要多少个成键电子,不好意思,是我们总共需要多少个电子,才能填满所有“八隅体“,那么这就应该是四乘上八,也就是三十二。
So that doesn't make a difference for us when we're talking about neutral atoms, 4s because we would fill up the 4 s first, because that's lower in energy until we fill it, and then we just keep going with the d orbitals.
所以那对我们来说没什么不同,所以当我们讨论中性原子时,因为我们会首先填充,因为在我们填充它之前它的能量都较低,然后我们继续填充d轨道。
So we actually only need two electrons to fill up the valence shell of hydrogen, remember that's because all we need to fill up is the 1 s.
我们其实只需要两个电子,就可以将氢的价壳层排满,要记得这是因为我们只需要排满,1,s,轨道。
s But it just turns out that the 4 s is so low in energy that it actually surpasses the 3 d, because we know the 3 d is going to be pretty high in terms of the three shell, and the 4 s is going to be the lowest interms of the 4 shell, and it turns out that we need to fill up the 4 s 4s before we fill in the 3 d.
但是结果是,能量较低,4s是第四层最低的,因为我们知道3d在第三层,是非常高的,4s是第四层,最低的,结果是我们在填充3d之前,需要先填充。
So we have two electrons in our bonding orbital, but because we use the same rules to fill up molecular orbitals as we do atomic orbitals, so the Pauli exclusion principle tells us we can't have more than two electrons per orbital, so we have to go up to our anti-bonding orbital here.
所以在成键轨道上有两个电子,但因为我们用了和原子轨道时,用的相同的规则,所以Pauli不相容原理告诉我们,一个轨道上不能有两个以上的电子,所以我们需要填充到反键轨道上去。
So now here's the idea. I build a list 256 elements long, and I fill it up with those special characters none.
所以这里就是这种思想6,我创建了一个可以放下256个元素的列表,然后我以这些没有实际意义的字符将其填充。
In particular, please go to it today, you will find a form there that you need to fill out to register for, or sign up for rather, a recitation.
特别声明,请今天就去看,你会找到需要填写的,一份注册表单,或者是复习课的签到表单。
So the Hund's Rule is telling us to put the two electrons in separate orbitals unpaired as opposed to we should not put them in like this, like some librarian might want to fill nicely from left to right, up and down.
所以洪特定律告诉我们,要把这两个电子放在独立的轨道中,而不是像我们常做的那样,像一些图书管理员想要,把书从左到右,从上到下放得很好。
px 2py So we need to fill all the way up to the pi 2 p x, and the pi 2 p y.
我们需要填到。
So if you want to on an exam, you can just write this down quickly at the beginning and refer to it as you're filling up your electron configurations, but also if you look at the periodic table it's very clear as you try to fill it up that way that the same order comes out of that.
如果你们想要在考试中,你们要在开始时快速地把这个写下来,然后在填充电子构型,的时候参考它,但是如果你们看着周期表,它就非常清楚了当你们将它用从那产生的,同样的顺序来填充。
