Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a . A macroscopic sample of an element contains an incredibly large number of atoms, all of which have identical . Atoms of one element differ in properties from atoms of all other elements. A compound consists of atoms of two or more elements combined in a . Atoms are neither during a chemical change; they're instead rearranged to yield substances that are different from those present before the change.
