• What is an atom


  Smallest particle of an element
• What does an atom consist of?

  protons, neutrons, electrons
• elements


  A molecule composed of one kind of atom; cannot be broken into simpler units by chemical reactions.

• mixture


  A combination of two or more substances that are not chemically combined (air)
• Molecules

  The atom can be an element or a compound
• Gas has more energy that liquid particles. Heat gives more energy to the particles and therefore diffuse quicker

• Solution


  the mixture of a solvent and solute
• Soluble


  a substance that dissolves in a solvent
• Insoluble


  A substance that does not dissolve in a solvent
• What is solubility


  A measure of how much solute can dissolve in a solvent at a given temperature
• Filtration


  Used to separate insoluble solids from liquids
• Evaporation


  Used to separate soluble solids from liquids
• Chromotography


  a process which separates the parts of a solution with special paper and a solvent.
