Substance (is) a single kind of matter that is pure, meaning it always has a specific makeup- or composition - and a specific set of properties.
Mixture (is) made of two or more substances- elements, compounds, or both- that are together in the same place but not chemically combined.
Molecules - groups of two or more atoms held together by chemical bonds.
Chemical Property (is) a characteristic of a pure substance that describes its ability to change into different substances.
Chemical Bond (is) a form of attraction between two atoms.
Heterogenous Mixture (is) a mixture in which pure substances are unevenly distributed throughout the mixture.
Chemical Formula shows the elements in the compound and the ratio of atoms.
Atom (is) The basic particle from which all elements are made.
Element (is) a pure substance that can not be broken down into any other substances by chemical and physical means.
Chemistry (is) the study of the properties of matter and how matter changes.
Solution (is) an example of a homogeneous Mixture; forms when substances dissolve.
Matter (is) anything that has mass or takes up space.
Physical Property (is) a characteristic of a pure substance that can be observed without changing it into another substance.
