It was a classical model, right, so we could say the electron is exactly this far away from the nucleus.
这是个经典模型,对吧,我们说电子离,原子核就是这么远。
If de Broglie is correct, we could then model the electron in its orbit not moving as a particle, but let's model it as a wave.
如果德布罗意是对的,那么我们可以在电子轨道中建立电子模型,不是像粒子一样运动,而是像波一样运动。
So, Lewis structures are really a model for a way to think about what the valence electron configuration is, and as I said, it's not based on quantum mechanics, it's something that Lewis observed far, far before quantum mechanics were discovered.
路易斯结构实际上是一个用来考虑价,电子排布的模型,而就像我说的,它并不以量子力学为基础,而是路易斯在以前发现的,在量子力学出现很早前。
Something like video games. So kids play video games but this model shop may continue to sell these complicated models. The next I want to show you is a sight I explore father-son relationship.
所以孩子们玩电子游戏,而这家模型店继续卖这些,复杂的模型,下面我要展示给你的是,是我探索父子关系方面的一段视频。
It means that we better get away from these deterministic models where we have a little electron here with its potential energy and its kinetic energy.
它的意思是我们最好远离,这些确定性模型,那里有一个小电子,它具有势能和动能。
This one is calculable by the Bohr model because lithium 2plus is a one electron system.
这个可以通过波尔模型计算而得到,因为锂2+是单电子系统。
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。
But no one dared say we have this little planetary model, I've got an electron orbiting a central nucleus and I am going to endow that electron with quantized states That was a big leap and that was Bohr in postulate five Postulate five I am just going to reproduce.
但是没有人敢说,我们拥有了这个小行星模型,知道了电子绕原子核运行,现在就要让它使电子处于量化的状态,假设五中波尔的成就是一个跳跃式的进步,假设五中我只需要重申一些东西。
And what he came out with when he did some calculations is that there's the radius that he could calculate was equal to this number a sub nought, which is what we call the Bohr radius, and it turns out that the Bohr radius happens to be the radius most probable for a hydrogen atom.
等于这个a0的值,我们叫它波尔半径,而,波尔半径恰好是,最容易,找到电子的地方,我们对波尔模型,不做过多的解释,这是因为。
