That happens because of space issues that you were asked to do that, because you can always assume that all of the core orbitals are already going to be filled.
这是出于空间的考虑,要求你这么做是因为,你总是可以假定所有的,芯电子轨道都已经填满了。
That's going to be filled out and articulated at great length in the subsequent chapters when all the laws they have to obey are spelled out.
条款将在后面的章节中,详细,准确的填写,所有应当遵守的规定都将阐明。
So, basically what he's showing in these cubes is that there are eight spaces that need to be filled up to have a full cube.
因此,基本上他在这里展示是这些立方体中一共有,八个位置,需要把它们都填满才得到一个完整的立方体。
Paradise Lost will be filled with the activity of eating.
失乐园里都是吃的活动。
for they shall be filled.
因为上帝会去充实他们。
They evolve to become very dense, hard, pustular lesions, which are filled with what turns out to be tissue debris.
它们逐渐变成粘稠,发硬,产生脓包状的伤痕,而这些粘稠的脓事实上是组织残骸
Surely must be pretty close to getting everyone filled in.
应该差不多每个人都填好了吧
So, he went to where people thought Troy might be and he began digging there, and before you know it, he discovered a mound filled with cities, which he believed was Troy.
因此,他来到人们认为的特洛伊城的所在地,然后,开始挖掘,然后你们知道的,他发现了土堆之中的城市,他相信那就是特洛伊城
So, for instance, they may be people like you who filled in a form, one question along a very long form was your sexual orientation, and then you're sitting down being interviewed by somebody and your interview is being filmed, and then other people are shown--who don't know you are shown the film.
他们可能是像你们一样在填一张表格,在一连串的问题中,有一条是关于你的性取向,然后你坐着,有人问你问题,这个提问过程会被拍下来,然后拿给别人看,这些人不认识你,他们会看这个录像。
This should make a lot of sense, because we know that a hydrogen has 1 s as it's outer-most or valence orbital, so it can be filled up just with two 1 s electrons.
这也是很合理的,因为我们,知道氢只有,1,s,轨道,这就是它最外层的轨道或者说价轨道,因此只要两个,1,s,电子就可以将它填满。
So this would be for the actual filled, the completely neutral atom.
因此,这就是中性原子,正确的电子排布。
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?
I don't care how you do it on exams or on problem sets, but you do need to be aware that the 3 d once filled is lower in energy than the 4 s, and the reason you need to be aware of that is if you're asked for the electron configuration now of the titanium ion.
我不关心你们在考试或者,问题集中如何做它,但是你们的确需要知道3d一旦被填充,它的能量是小于4s的,你们需要知道这个的原因,是如果你现在被要求,写出钛离子的电子构型。
You wouldn't be expected to be able to guess that this would happen, because using any kind of simple theory, we would, in fact, predict that this would not be the case, but what we find experimentally is that it's more stable to have half filled d orbital than to have a 4 s 2, and a 3 d 4.
你们不用预期有能力,猜出这个会发生,因为使用任一种简单的理论,我们事实上可以预测不会是那种情况,但是我们在实验中发现的,是半填充d轨道比,4s23d4更加稳定。
