polar describes a molecule with opposite charges on opposite ends non-polar molecule that shares its electrons equally; does not have areas of charge acid compound that forms hydrogen ions (H+) in solution base compound that produces hydroxide ions (OH-) in solution p...

Atom The basic unit of all matter that consits of three subatomic particles-neutrons, protons, and electrons. Nucleus The center of an atom which contains the protons and neutrons; in cells, structure that contains the cell's genetic material (DNA) and controls the cell's activities. ...

molecule the smallest unit into which an element can be subdivided and still have the essential chemical properties. elements substances that cannot be broken down chemically into simpler substances atoms the smallest unit of an element that still had the chemical properties of that...

organisms living things that are composed of chemicals and that an understanding of life requires an understanding of chemistry. Molecules the smallest units into which water can be subdivided and still have the same properties of water. Elements substances that cannot be broken dow...
