And so, for today, for example, it says Classification Schemes, Mendeleev, Atomic Structure, A Readings Chapter 1, Chapter 2, Appendix A.
今天,举个例子,讲的是分类法,门捷列夫,原子结构,阅读第1,第2章,和附录。
Step three in our Lewis structure rules is to figure out how many electrons we would need in order for every single atom in our molecule to have a full valence shell.
路易斯结构规则的第三步是,找出让分子中每个原子的价壳层,都排满应该需要多少个价电子。
There was a lot of physics going on, but we didn't know a whole lot about atomic structure back in those days.
物理学在迅速发展,但在这之前并没有人对,原子结构有很全面的了解。
It's as if this celestial laser beam were designed so as to actually shift the atomic structure of the pure corporeal frame of the virgin's body until that body is so rarefied, so pure and ethereal, that it's nothing but soul.
这束天国的激光好像被设计成,去把处女纯净肉体的原子结构,变的纯化,纯粹和飘渺,那就是灵魂。
When I posit the existence of atoms with certain structures and certain sort of ways of interacting and combining and building up, when I posit atoms, suddenly I can explain all sorts of things about the physical world.
当我假设原子以某种特定结构存在,以一定的方式相互作用,互相结合,集聚,通过假定原子存在,我立即就能够解释,物理世界中各种各样的现象了
In terms of picking a Lewis structure that's going to be the lowest energy, what you want to do is put the atom with the lowest ionization energy in the center of your atom.
为了挑选一个具有,最低能量的路易斯结构,你需要把电离能最低的原子,放在最当中的位置。
So, which atom would you expect to be in the center of a Lewis structure for thionyl chloride?
那么,大家认为那个原子应该在,亚硫酰氯的路易斯结构的中心位置呢?
But what I'm going to tell you already is this is a case where, in fact, it's an exception to the idea that the lowest energy structure has the lowest ionization energy in the middle, and we can figure this out when we look at formal charge.
但是我已经告诉大家这个例子,实际上,是中心原子电离能最低的结构,的能量最低这一思路的一个例外,我们可以通过形式电荷看出这一点。
And in its stead Rutherford proposed something akin to a planetary system.
而卢瑟福提出的,和行星系统相似的原子结构取而代之。
Now, for example, in our structure with ozone it's between all three atoms.
比如,在我们的臭氧的结构中,它们是在所有三个原子之间的。
Professor Rutherford has given a theory of the structure of atoms.
卢瑟福教授给出,原子结构的理论。
When we talk about resonance structures, we're talking about cases that have the same arrangement of atoms the key is the atoms are the same, and the thing that is different is the arrangement of electrons here.
当我们讨论共振结构的时候,我们讨论的是原子排布相同情况,关键在于原子是相同的,不一样的只是电子排布。
So for some you that are less interested in maybe the physical structure of an individual atom, now some more exciting material for you might be coming up if you like to think about how, instead, molecules behave, either within bonding, within themselves, or with other molecules, that's what we're going to be heading to in this next unit.
那么对于某些同学,你们或许不感兴趣,对于单个原子的物理结构,现在可能有令你感到兴奋的内容,要出现了,如果你更喜欢思考,分子的行为,或者是关于成键的,或者是关于它们本身的,又或者与其它分子之间的行为,这些将是我们下个单元要讲的内容。
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。
So, we need to fill our octet for selenium, so 1, 2, 3, 4.So, this is our Lewis structure here, hopefully you can see why it's not linear.
我们要填满硒原子的八配位,所以1,2,3,4。这就是Lewis结构,希望你们能看出来为什么它不是直线型的。
