【How is the atom?】

《An electron's electric charge》

The things which look like clouds are the ones made from electrons.The electron is β rays' essence.😃

One electron has minus electric charge of one unit.We express it like -1.If the electric clouds are made from a number of z,it has electric charge of minus z as a whole.☁

There is the atomic nucleus in the center of the clouds.Its electric charge is the number of plus z,so the atom is neutral electrically.We call the number of the z an atomic number.💡

《Size of the atom and atomic nucleus》

The atom is extremely tiny.If we compare the atom to a ping-pong ball,the ping-pong ball which is magnified with the same rate becomes a size of the earth.🌏
　　　　　　　　
The atomic nucleus is by far tinier than the atom,roughly speaking,its diameter is one-hundredth times as minimum as the atom.😃

In short,if the diameter of the atomic nucleus is 10cm,that of the atom is 10.000cm,100m.😲
