Atom economy or atom utilization is simply the Mr or molecular weight of desired product formed divided by the Mr of all the reactants.
Say we have a reaction A + B -----> C C + D ------> E
AU = (Mr of E/(Mr of A + B + C)) x 100
The atomic weight minus the number of protons = the atom's neutrons.
The percentage yield shows the percentage of the actual amount of product you got from the amount of product you ought to get. A reaction can have a high percentage yield while at the same time producing much waste. So as an alternative, the idea of atom economy was put forward as a better measure of a synthesis efficiency. Atom economy shows the percentage of the desired products from the total amount of reactants.
the Atomic Mass number is the number of protons/electrons in an atom
Industrial reactions with high atom economies produce less waste, reducing environmental impact and making the process more sustainable. High atom efficiency also leads to higher yield of desired products, increasing the overall efficiency and reducing production costs.
The atomic number (1 to 114) in the periodic system is equal to the number of protons.

The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
i am not sure
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps
The atomic weight minus the number of protons = the atom's neutrons.
Protons and neutrons= mass
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
The atom economy of a reaction measures the efficiency of how atoms are utilized in producing the desired product. For the synthesis of ammonia (NH3) from nitrogen and hydrogen gas, the atom economy is 33.3%, meaning that one-third of the reactants' atoms end up in the product molecule.
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.

The number of protons and neutrons in the nucleus
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
