Consider a neutrally charged atom that has an atomic mass number of 80, which includes 35 neutrons. how many electrons does this
ivanzaharov [21]
Atomic mass number is the number of protons and neutrons. Subtract 80-35=45 is the number of protons. Because the atom is neutrally charged, the number of protons must equal the number of electrons, so there are 45 electrons.
