2. The Classification of Matter

3. Pure Substances (All particles are identical and can be chemically separated)
Elements
made of only one type of particle
Metals
found on the left side of the periodic table (e.g. gold - Au)
Non-metals
found on the right side of the periodic table (e.g. oxygen - O)
Metalloids
have properties of both metals and non-metals (e.g. silicon - Si)

4. Pure Substances Compounds made of two or more types of particles
Inorganic (non-living)
Ionic (metal + non-metal elements)
e.g. salt (NaCl)
Polyatomic (3 or more elements)
e.g. chalk (CaCO3)
Covalent/Molecular(2 non-metal elements)
e.g. water (H2O)
Organic (living)

5. Mixtures (Contains different particles mixed together that can be physically separated)
Homogenous
one visible phase in either a liquid solution or a solid metal alloy
e.g. koolaid or brass
Heterogenous
two or more visible phases involving solids or a liquid colloids
e.g. sand or milk
