WebCompounds. A compound is a pure substance that can be decomposed into simpler substances because it is made up of 2 or more elements. For example, water is made up of two different elements; hydrogen (H) and oxygen (O) An electric current can be passed through water to decompose (break up) water into the elements hydrogen and oxygen.
