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。

But luckily for us, there's a classical equation of motion that will, in fact, describe how the electron and nucleus change position or change their radius as a function of time.

但幸运的是，有一个,经典方程描述了电子和核子,位置或者它们直接的距离是,如何随时间变化的。

And, as I mentioned, we left off and as we started back here to describe the atom and how the atom holds together the nucleus and the electron using classical mechanics.

我之前提及过，我们上次,讲到应用经典力学如何描述,一个原子以及原子如何把质子,和电子束缚在一起，今天我们要。

So think about what that means, we're, of course, not talking about this in classical terms, so what it means if we have an electron in the 2 p orbital, it's more likely, the probability is that will be closer to the nucleus than it would be if it were in the 2 s orbital.

想想这意味着什么，我们不是从经典的角度考虑，这意味着如果我们有个电子在2p轨道上，它更有可能比在2s轨道上,更加靠近原子核。
