  • Particles
    • States
      • Soilds
        • close together
        • regular pattern
        • held together by bonds
        • vibrate in fixed position
        • cannot move from place to place
      • Liquids
        • random arrangement
        • close together
        • they can move around eachother

        • randomly arranged
        • move in all directions
    • Naming Compounds
      • 2 elements
        • ending is - ide
      • 3 or more
        • ending in something -ate
      • 2 identical elements
        • doesn't change
    • Rocks
      • Igneous
        • Formed when molten magma  is pushed up to the surface
        • contain various minerals
        • 2 types
          • Extrusive
            • cools above ground
          • Intrusive
            • cools underground
      • Sedimentary
        • Formed from layers of sediment
        • layers cemented together by other minerals
        • Fossils can form in sediments
      • Metamorphic
        • Formed when heat and pressure are exerted on rocks over long periods of time
        • some have layers
