compounda pure substance made up of atoms of 2 or much more different elements joined with each other by chemical bonds.
mixturea combination of 2 or more subtances that room not chemically combined. Not a pure subtance.
pure substancea sample of matter, either a single element or a solitary compound, that has actually definite chemical and physical properties.
