原子核的电荷量是多少？

What is the charge of the nucleus?

有原子核的面积,通过除以所有原子的,总面积。

So, here we have the area of the nuclei we'll figure out adding those all together versus the space of all of the atoms put together.

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。

We are talking about probability, but what we're saying is that most probable radius is further away from the nucleus.

我们说的是概率，也就是说它的最可能半径,离原子核更远。

And so the other thing that we consider is the nucleus as being stationary.

接下来我们讲的是,原子核是静止的。
