∙ 12y agoIf you're talking about pure substances, then the answer is atoms. Some pure substances are composed of only one kind of atom and are called elements. Compounds are pure substances composed of atoms of more than one element. Examples of elements include hydrogen (H), oxygen (O), and carbon (C). Examples of compounds made with those elements would include glucose (C6H12O6) and sucrose (C6H22O11).
