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。
