Rule for determining mass number of atom

WebbAtomic mass is the sum of all the protons, neutrons, and electrons in a single atom or molecule. However, the mass of an electron is so small, it is considered negligible and not included in the calculation. WebbThe 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 electrons is 54 ...

WebbThe total number of protons and neutrons (known collectively as nucleons) in the nucleus of an atom is known as the mass number or atomic mass number or nucleon number. It is expressed in atomic mass units. The letter 'A' is used to signify it. Mass Number The mass number is different for the isotopes of the same element. Webb10 sep. 2024 · For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
