In fact, it's actually possible to have an atom consisting of … Photo-dissociation: 9Be( γγγ,n)2 α-1.66 MeV 4. The number of protons in the nucleus of an atom is its atomic number (\(Z\)).This is the defining trait of an element: Its value determines the identity of the atom. Because electrons have virtually no mass, just about all the mass of an atom is in its protons and neutrons. Because neutrons and protons both have a mass of about 1 amu, the difference between the mass number (210) and the atomic number (82) is equal to the number of neutrons in the nucleus of the atom.    Electron Configuration    Transition Metals Many isotopes have radioactive nuclei, and these isotopes are referred to as radioisotopes. but the real question is how to i find out how much protons and electrons an element has?
