WebThe binding energy that holds the protons and neutrons together comes from some amount of mass such that E=mc^2. If you change the number of bound neutrons or protons, you also change the energy required to bind them together, thus the total mass changes. This is also why individual, unbound protons or neutrons have a mass more than 1 u. WebAverage atomic mass = f 1 M 1 + f 2 M 2 +... + f n M n where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.
