  • Atoms
    • The nucleus
      • It contains protons and neutrons
      • In the middle of the atom
      • It has a positive charge because of the protons
      • Almost the whole mass of the atom is concentrated in the nucleus
    • The electrons
      • Move around the nucleus
      • They are negatively charged
      • They're tiny, but they cover a lot of space
      • The volume of their orbits determines how big the atom is
      • They virtually have no mass
      • They're arranged in shells around the nucleus
    • Know your particles
      • protons are heavy and positively charged
      • neutrons are heavy and neutral
      • electrons are tiny and have a negative charge
    • number of protons equals number of electrons
      • neutral atoms have no charge overall
      • The charge of the electrons is the same size as the charge on the protons-but opposite
