Front 1

Mixture

Back 1

an aggregate of two or more substances that are not chemically united and that exist in no fixed proportion to each other.

Front 2

Substance

that of which a thing consists; physical matter or material

Front 3

Compound

Back 3

composed of two or more parts, elements, or ingredients

Front 4

Element

Front 5

Atom

Back 5

a.
the smallest component of an element having the chemical properties of the element, consisting of a nucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleus by electrical attraction; the number of protons determines the identity of the element.

Front 8

Matter

Back 8

physical or corporeal substance in general, whether solid, liquid, or gaseous, especially as distinguished from incorporeal substance, as spirit or mind, or from qualities, actions, and the like.

Front 9

Heterogeneous

Back 9

(of a mixture) composed of different substances or the same substance in different phases, as solid ice and liquid water.

Front 10

Homogeneous

Back 10

composed of parts or elements that are all of the same kind; not heterogeneous:
