Structure of atoms

This universe is composed of about 100 kinds of atoms. The size of a typical atom is about 10-10m. An atom is composed of electrons rotating around a nucleus and a nucleus, which is about 10-5 times the size of an atom, but accounts for almost 100% of the atomic mass. The atomic nucleus is also a proton with (+) charge and an electrically neutral neutron.
