Atom efficiency is a ratio used in green chemistry to analyse the efficiency of a reaction.
Additional recommended knowledge
The ratio is measured as (mass of atoms in product)/(mass of atoms in reactants). An assumption in doing this calculation is that the yield is 100%, which is very rare.
For a reaction to be 100% atom efficient, all the atoms of the reagents used must be incorporated into the desired product. Addition reactions, such as hydrogenation of an alkene, for example are 100% efficient. Reactions that result in a undesired by-product are less atom efficient.
