Matter - ANS anything that has mass ans takes up space.
Atoms - ANS building blocks of matter, and they are the smallest form of matter other than
subatomic particles.
Element - ANS all made up of the same kind of atom for one element.
Molecule - ANS two or more atoms held together by covalent bonds, in specific shapes.
Compound - ANS made up of two or more different elements that are combined.
3 forms of matter - ANS solid, liquid, gas
Gas - ANS no fixed volume, easy to compress
Liquid - ANS distinct volume, compressible but not as much as gas
Solid - ANS fixed shape and volume, not compressible.

, Pure substance - ANS usually referred to as substance, has distinct properties and a
composition that does not vary from sample to sample. 2 types of pure substances: elements,
and compounds.
2 forms of pure substance - ANS Element: a substance that cannot be decomposed to simpler
substances. EX: anything on the periodic table of elements.
Compound: a substance which can be decomposed into simpler substances. EX: H2O, (it can be
broken down)
Mixture - ANS Exhibit the properties of the substances that make them up. 2 types:
Heterogenous and Homogenous.
2 types of mixtures - ANS homogeneous: also known as solution, their compositions do not
vary throughout a sample. EX: coffee, or smoothie, you can't see the milk and coffee and sugar
separated.
heterogeneous: their compositions vary throughout a sample. EX: Pizza, you can pick the
pepperoni from the cheese or sauce, another example would be granite countertop because
you can see the different types of rocks.
Heterogeneous - ANS their compositions vary throughout a sample. EX: Pizza, you can pick
the pepperoni from the cheese or sauce, another example would be granite countertop because
you can see the different types of rocks.
Homogeneous - ANS also known as solution, their compositions do not vary throughout a
sample. EX: coffee, or smoothie, you can't see the milk and coffee and sugar separated.
Physical properties of Matter - ANS can be observed withOUT changing a substance into
another substance. EX: boiling point, density, mass, volume
Chemical properties of Matter - ANS Can only be observed when a substance is changed into
another substance. EX: flammability, corrosiveness, reactivity with acid.
