Properties of Metals Science Lesson | HST Learning Center
An element is a substance made up of one kind of atom; it cannot be separated into simpler parts. For example, the element helium (think hot-air balloons) is made up exclusively of helium atoms. Elements are generally classified as metals or nonmetals (although some elements have characteristics of both; these are called metalloids ).
