And out of that came the recognition that Thompson's plum pudding model is not sustainable in the light of this evidence.
从中我们得出,汤姆生的枣糕布丁原子模型,是不合理的。
We ended the day with Bohr's model of the atom, which derived from the conceptualization of Rutherford.
那天课的结尾我们讲了从卢瑟福的概念中,衍生出来的波尔的原子模型。
So, what he did was kind of impose a quantum mechanical model, not a full one, just the idea that those energy levels were quantized on to the classical picture of an atom that has a discreet orbit.
还不是完整的,只是这些能级,是量子化的概念,作用到原子有分立轨道的经典原子模型上,当他做了一些计算后,他得到有个半径,他算出来。
And what I am going to do today is go in some detail through the Bohr model, so let's do that.
今天我想具体介绍一下波尔的原子模型,那我们现在就开始吧。
These are the planks of his model, that matter is composed of atoms that are indivisible and indestructible.
这些是,他的模型的一些内容,物质是有原子组成的,不可分割且不可毁灭的。
OK, this is the Bohr model, Bohr model of the atom is planetary or nuclear.
好的,这就是波尔模型,波尔的原子模型是行星模型或者核心模型。
Now, let's take a look at the Bohr model of the atom.
让我们看看波尔的原子模型。
Great interest is to be attributed to this atom model."
这个原子模型引发了极大的兴趣“
So, this is exactly how Rutherford did discover that these particles were present and made this new model for the atom that we now know has both a nucleus, and we know the size, and also has electrons.
他提出了一个,新的原子模型,这里面有一个原子核,和一个电子,原子核的尺寸是知道的。
All right, July, 1913, blow this up, so On the Constitution of Atoms and Molecules by N. Bohr, Doctor of Philosophy, Copenhagen, asterisk here, and I've blown up the bottom of the page, communicated by Professor Ernest Rutherford, F.R.S., Fellow of the Royal Society.
913年,六月,发表了,波尔博士,建立了原子分子模型,哥本哈根,星号这儿,我通过和恩内斯特卢瑟福的交流,被这页底部的所震惊了,英国皇家学会会员。
So, I said I'd tell you a little bit more about where this Bohr radius came from, and it came from a model of the atom that pre-dated quantum mechanics, and Neils Bohr is who came up with the idea of the Bohr radius, and here is hanging out with Einstein, he had pretty good company that he kept.
我要告诉你们,波尔半径是从哪里来的,它起源于前量子力学时代的,原子模型,尼尔斯,玻尔提出了,波尔半径的概念,这是他和爱因斯坦在一起,他们是好朋友,当我们讨论这个原子模型时你们要记住的是,在1911年。
That's why in the earlier models of the atom, they're not horrible to sometimes think about just each n value as a little ring around.
这就是为什么在早期原子模型中,人们没有感觉到把每一个,n,都想象成,一个绕核的小圆圈有什么不妥。
So, what he could conclude thus far was that this was really consistent with the Plum Pudding model. All of his heavily-charged alpha particles were going right through this thin layer of gold atoms.
和布丁模型是吻合的,所有的重alpha粒子,都穿过金原子,你们也许会觉得,他可以就此。
So, Thomson came up with a model for the atom due to this, and this is called the Plum Pudding model of the atom, and he was, as we said, English, so plum pudding is kind of a British food.
所以Thompson因此,想到了一个原子模型,他把它叫做,李子布丁模型,我们说过他是英国人。
And I picked looking at methane so we could see if there are other factors that we're not considering, that we need to maybe tweak our model a little bit, and I think we'll find that we do if we take a look at a polyatomic molecule, methane, CH4 so c h 4.
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。
