WebThe nucleus is made up of protons and neutrons. Therefore, atomic mass refers to the total mass of protons and neutrons. Atomic mass (A) = Nucleus mass = Total mass of protons and neutrons (p + n) Again, the mass of each proton and neutron is about 1amu. Therefore, the total number of protons and neutrons is called the atomic mass number. Web28 jul. 2024 · 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 …
