  - - - Cannot be dissolved in water
- - - - particles are not distributed evenly
        
        PHASE - any part of a sample that has a uniform composition and properties.
        
        HETEROGENEOUS - 2 OR MORE PHASES
        
        HOMOGENEOUS - SINGLE PHASE
  - - - portions of material in the same state, no visible boundaries
        
        Ways to seperate homogeneous mixtures: destillation, crystalization, chromatography
- - - - reactions
      - composition of atoms/molecules are changed
      - Forming into another substance
    - - Chemical composition doesn't change
      - FREEZING AND MELTING POINT
      - shape, STATE, COLOUR
- - - - second region of the atom is a "cloud" of electrons that orbit around the nucleus
    - - dense region consisting of protons and neutrons at the center of an atom
        
        protons- positively charged
