chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. water molecule A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons.
Chemical properties of matter describe its potential to undergo some chemical change or reaction by virtue of its composition. The elements, electrons, and bonds that are present give the matter potential for chemical change.
A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Elements and compounds are both examples of pure substances. Elements are the simplest substances made up of only one type of atom.
