WebThe atomic mass of an atom is the sum of all the subatomic particles present in it. As we all know, an atom consists of protons, neutrons, and electrons. Many other subatomic particles are also a part of an atom. Still, since their weight is almost negligible, we don't count them up while calculating the atomic mass of an atom. 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.
