We have a table of the elements with properties varying periodically with atomic mass, so we compress all of that information and refer to it as the Periodic Table.
我们有一个元素表，其中的元素的特性,随着原子质量的改变而引起周期性的变化，所以我们将所有的信息精简,将它变成一个周期表。

I mean they take up a teeny bit but essentially when we're thinking about the set up of the atom, we don't have to account for them as using up a lot of the mass we're discussing.
所以我们可以假设电子没有质量,它们占据了，非常小的一部分,所以当我们考虑,原子的构造的时候,不用考虑它们的质量。

And so we know the force for a particular mass, and we know the area of the piston.
我们知道每个质量对应的力，也知道活塞的面积。

-
If we think of the size of a typical atom, we would say that would be about 10 to the negative 10 meters. So, we can see the diameter of a nucleus is absolutely smaller really concentrating that mass into a very small space.
一个普通细胞的大小，抱歉，我和细胞核搞混了0,如果我们考虑，一个普通原子的大小,这大概是10的负十次方米,所以原子核的直径确实非常小,真的是把质量。
