The Elements Matter composed of only one kind of atom, where all atoms of the same kind have the same properties.

The Elements 90 different types exist naturally on Earth Almost all known matter is composed of them Common examples: H He O2 Na Cl Fe Au sodium chlorine

The Elements An elemental substance can not be broken down by chemical processes An elemental substance can not be converted into a different element by chemical processes “allotropes” of pure carbon graphite diamond charcoal

Matter Flow Chart

Compounds Two or more different types of elements - chemically bonded together - in fixed proportions.

Compounds Common Examples: H2O CO2 CO CH4 NaCl C8H18 octane C12H22O11 sugar C8H10N4O2 caffeine

Compounds What determines the compound: • The elements involved • The ratio of the elements H2O vs H2O2 CO2 vs CO N2O vs NO2 CO vs Co

Compounds To form a compound (from its elements) or - to separated a compound (into its elements) a chemical reaction is needed!

Matter Flow Chart

Homogeneous Mixtures A mixture that is uniform in its properties through out any given sample. It is completely mixed! “Solutions”

Homogeneous Mixtures Examples: Solids Alloys - metallic mixtures Brass (Cu and Zn) Bronze (Cu and Sn) Steel (Fe, C, etc.) Pewter (97% Sn, Cu, Bi) (Used to be Pb and Sn)

Homogeneous Mixtures Examples: Liquids salt water tea sugar water pop apple juice The liquid must be “clearly transparent”

Homogeneous Mixtures Examples: Gases Air (N2 and O2, and others) “Trimix” (N2, He and O2 for deep scuba) Any combination of gases will mix thoroughly

Homogeneous Mixtures Separated by physical processes: Examples: Evaporation

Homogeneous Mixtures Separated by physical processes: Examples: Reverse Osmosis

Homogeneous Mixtures Separated by physical processes: Examples: Distillation

Matter Flow Chart

Heterogeneous Mixtures A mixture that consists of physically distinct parts, each with different properties. Not mixed very well! “Chunky”

Heterogeneous Mixtures Examples: Granite Rocky Road Ice Cream Soil Lasagna Oatmeal

Heterogeneous Mixtures Also separated by physical processes: Examples: Filtration Floatation Also, any method that works on homogeneous mixtures, would also work on heterogeneous mixtures
