So you might ask well, why are we using this model if it clearly doesn't take into account quantum mechanics?

那么大家可能会问为什么我们要用这个,显然没有考虑量子力学的模型呢？

That's a deterministic way of doing things, that's what you get from classical mechanics.

与核子的半径,是从经典力学中得到的，但我们从量子力学模型，知道的事实是。

He knew the same thing that had been observed by that point.

所以他所做的就是,把一个量子力学的模型。

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。

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。
