Structure of an atom

Atoms are basic building blocks of matter. Every body consists of atoms or molecules.

The structure of an atom is roughly divided into the nucleus, which consists of neutrally-charged neutrons und positively-charged protons and the electron shell, which contains the negatively-charged electrons. According to the Bohr model these electrons move on circular orbits around the nucleus.
