symbol, eg ‘O’ represents an atom of oxygen. There are about 100 different elements. Elements are in the periodic table. Compounds are formed from elements by chemical reactions. Chemical reactions always involve the formation of one or more new substances, and involve a detectable energy change. Compounds contain two or more elements chemically combined in fixed proportions and can be represented by formulae using the symbols of the atoms from which they were formed. Compounds can only be separated into elements by chemical reactions. Chemical reactions can be represented by word Name compounds of these elements from given formulae or symbol equations.
