  • Atoms
    • The nucleus
      • in the middle of an atom
      • it contains protons and neutrons
      • it has an overall positive charge because protons are positively chargeed and neutrons have no charge
    • Electrons
      • they occupy shells (energy levels) around the nucleus
  • tiny comapred to the whole atom
    • The nucleus
      • in the middle of an atom
      • it contains protons and neutrons
      • it has an overall positive charge because protons are positively chargeed and neutrons have no charge
  • move around the nucleus
    • Electrons
      • they occupy shells (energy levels) around the nucleus
  • negatively charged
    • always equal the number of protons
      • protons - heavy & positively charged
        • neutrons - heavy & neutral
