Atomic Structure

Atoms the building blocks of all matter. They are made up of protons, neutrons, and electrons.
Element a pure substance-made up of only one type of atom
Nucleus the center of the atom and contains protons and neutrons, this is where the mass of the atom is located
Proton particles that have a positive (+) charge, located in the nucleus
Neutron particles that have no charge, they are neutral, located in the nucleus
Electron particles that have a negative charge, located outside of the nucleus and travels around the nucleus in shells or orbitals
Atomic Number tells you the number of protons in the nucleus and the number of electrons in the electrons cloud. It is always located at the top of the periodic square.
Atomic Mass tells you the number of protons and neutrons that are in the nucleus of the atom
Electron Shells or Energy Levels this is the area in which electrons travel at high rates of speed, each shell or level has a certain number of electrons that it can hold
How do you find the number of protons and electrons in an atom? look at the atomic number
How do you find the number of neutrons in an atoms? to find the number of neutrons in an atom you MUST subtract the atomic number FROM the atomic mass
