==Key Stage 4==
===Meaning===
'''Atom Economy''' is the [[percentage]] of [[atom]]s in the [[reactant]]s which ends up in the desired [[product]]s.
===About Atom Economy===
: During a [[Chemical Reaction|chemical reaction]] there is often more than one [[product]]. When there is more than one [[product]] often one is desired and one is a [[Waste Product|waste product]] that must be [[disposal|disposed]] of.
: To reduce costs and increase the [[efficiency]] of a process [[Chemical Engineer|chemical engineers]] design systems that [[product|produce]] the maximum amount of a desired [[product]] and a minimum amount of [[Waste Products|waste products]].
===Atom Economy Equation===
Percentage Atom Economy = [(Relative Formula Mass of Desired Product)/(Sum of Relative Formula Masses of Reactants)] x 100%
% Atom Economy = <math>frac{M_desiredproduct}{M_allreactants}</math>
Where:
M<sub>desiredproduct</sub> = Relative Formula Mass of Desired Product
M<sub>allreactants</sub> = Sum of Relative Formula Masses of Reactants
