Substance
Something you cannot break into simpler parts using physical changes.
Molecules and compounds.
Molecule
A combination of two or more atoms.
Compound
Two or more elements chemically combined.
Elements are in specific amounts as seen in their chemical formula (ex. H₂O).
Can only be broken down with chemical reactions.
Mixture
Two or more substances physically combined in any amounts.
They do not change chemically.
Heterogeneous and homogeneous mixtures.
Heterogeneous
Mixture
Two or more substances that aren’t evenly mixed, you can see different parts.
