1. of Matter

2. Names and formulae

   • Metals
   • Metalloids
   • Non-metals
   • Left usually 1st
   • Right add suffix
   • polyatomic ions (same ratio of elements have common name)
   • Positive ions 1st

3. Mixtures

   • Components not in fixed ratio Separated by physical means Components keep own properties
   • Homogenous
     • Components all in same state
     • Uniform composition
     • Cannot distinguish
   • Heterogenous
     • Components not in same state
     • Components distinguishable
     • Non-uniform composition

4. Properties

5. Pure substances

   • Compounds
     • ≤ 2 types of atoms
     • Chemically bonded atoms
       • Can only be broken down chemically
   • Elements
     • 1 type of atom
     • Particles can't break down
   • Only 1 type of particle

6. What is matter?

   • occupies space
   • has mass
   • Solid, liquid & gas
   • small particles of periodic table determine reactivity and properties of substance
