Good rules about the mass of your atom or ion
WebSolution. The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of ... WebThe amount of the electrons have to be more than the amount of the protons. Rule #4: Mass The number of electrons do not affect the mass; however, the more protons and neutrons you add to the atom, the bigger the mass gets. The number on the bottom of the box for the elements is the mass of the element.
