Structure of the atom

• The structure of the atom contains 3 small particles that each have their own charge
• In the center of the atom there are protons and neutrons
• Protons has a +1 charge where else neutrons have a 0 charge
• Outside of the nucleus is the electron with their -1 charge
• Usually in an atom the number of protons equal to the number of electrons
•  is commonly the symbol for electron,  symbolizes proton and  symbolizes neutrons
• Number of neutrons is commonly calculated using the difference of the atomic mass and the number of protons
• Electrons are always on the outside and circle the nucleus in their corresponding valence shell
