A compound is a substance made from two or more elements that have reacted chemically with each other. Remember this definition as you might need it in the exam! A compound is a completely new material that will often have totally different properties from the elements that made it. For example The element sodium is a highly reactive metal. The element chlorine is a yellow-green poisonous gas (non-metal). When the two react together they form a compound called sodium chloride.
A chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be chemical elements, chemical compounds, ions or alloys. chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice. Compounds based primarily on carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds.
