The symbol for each atom is identified. Concept Introduction: Mass number : The sum of protons and neutrons gives the value of atomic mass . A (mass number) = no .of protons (P) + no .of neutrons (N) The element symbol : Z A X where, A (a...
The difference between the masses of the proton and neutron comes from the difference between the experimental masses and the theoretical masses of quarks up and down. Straightforwardly, we found theoretical values of the masses of protons and neutrons within 2% of the experimental values of the ...
