Pure SubstancesComposition is the same throughout
and does not vary from sample to sample.
CANNOT be broken down by physical changes
Can be an element or
compound.
ElementDefinition: substances in their simplest formsCannot be broken down by a physical or chemical change
Found on the periodic tableMade up of one type of atom
Examples of Elements:HydrogenCarbonLithiumGold
What are two other examples of elements not listed above? What do all elements have in common?
CompoundDefinition: substance formed by the
chemical combination of two or more elementscan be broken into simpler substances by a chemical change
+ = Compound
A compound is always composed of the same elements in the same proportions.
In other words, Carbon Dioxide (CO2) is always composed of 1 atom of C and 2 atoms of O.
If there are different amounts of carbon or oxygen, it is no longer carbon dioxide.
Law of Definite Proportions
More Examples of Compounds
MixtureDefinition: two or more pure substances (elements or compounds) that are mixed
together but NOT joined chemicallyNOT a pure substanceExamples: The air we breath, gasoline for cars, the sidewalk on which we walk
Homogeneous MixturesUniform in composition and
appearance
Same proportion of components throughout
Consists of two or more substances in the same phase
Also called solutions
Heterogeneous Mixturesvariable appearance and composition
