【How is the atom】

《Size of the atom and the atomic nucleus》

Let's suppose that the atom were a shape which two domed baseball stadiums like two small pancakes with bean jam in between どら焼き.Then the atomic nucleus is a size of the ping-pong ball on a pitcher plate on the domed baseball stadium.⚾

By the way,I've never seen the electric cloud around the atomic nucleus.I've expressed『clouds』,but I'm wondering if it's a single cloud which surrounds around the atomic nucleus,though I'm not sure of it at all.😚

【How is the atomic nucleus?】

The atomic nucleus is also very tiny.It's in the center of the atom,99% of the atom's mass is the atomic nucleus.😃

In a word,the electron has a great volume as if it were a cloud,but it had little substance.On the other hand,the atomic nucleus has crowded density.😃

The atomic nucleus is also deeply related with radioactivity.☝
