This is the lithium nucleus plus electron.

这是锂原子核加上一个电子。

We have an orbiting electron but a stationary nucleus.

我们有一个在轨运行的电子和一个静止原子核。

That is the electron in its lowest orbit, to the nucleus of atomic hydrogen.

那就是氢原子原子核外电子，最低轨道到情况。

youdao

And the way that we'll do this is starting with talking about the discovery of the electron and the nucleus here.

在这之后,我们就可以通过,经典力学来描述一个原子。

And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.

然后说势能,位能其实就是,由电子和原子核之间的库仑引力而形成的能量。

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。
