... Atoms are composed of three fundamental particles: the proton (1 amu, +1 charge), the neutron (1 amu, 0 charge), and the electron (~0 amu, charge). The number of protons in the nucleus of the atom is called the atomic number (Z) and defines the element. The sum of the number of protons and neutrons ...
