substancecompounds
Substance compounds, commonly referred to as chemical compounds, are pure substances composed of two or more elements bound together by chemical bonds in definite, fixed ratios. The chemical formula of a compound expresses the proportion of each element, and the compound’s properties—such as melting and boiling points, density, and reactivity—are typically distinct from those of its constituent elements.
Compounds differ from mixtures in that their components are chemically bonded and cannot be separated by simple
Classification often follows the type of chemical bonding. Ionic compounds form through electrostatic attraction between positively
Naming and representation rely on established conventions. Compounds are given systematic names or common names, and
