Recall that Matter can be categorized as a single or variable composition.

• Matter is considered a pure substance if it is composed of a single entity. Pure substances can be further categorized into two:

Element  cannot be separated into simpler substances or composed of only 1 type of atom (eg. O3, Cl2)
Compound  can be separated into simpler substances

• Matter is considered a mixture if they have variable composition. Mixtures are not chemically combined. Mixtures can be further categorized into two:
