Use the same formula, mass number minus atomic number, to calculate the number of neutrons. In the case of mercury, the most common isotope is mercury-202. Use the equation, 202-80=122, to find that mercury-202 has 122 neutrons. …

WebAlpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. An alpha particle is identical to the nucleus of a helium-4 atom, which … WebThus, we generally consider both mass number and atomic mass to be the same. Therefore, atomic mass = number of protons + number of neutrons If we subtract the … duty train to berlin

WebThe other neighbouring isobar (same mass number, different atomic number) to argon-40 is also of lower mass, 39.962384, than potassium-40. This mass difference converted to energy units gives an energy release of 1.5 MeV, ... atomic mass. The mass of the parent minus the sum of the masses of the decay products gives the energy release. WebThe mass number of an atom is equal to the total number of protons and neutrons contained in its nucleus. This definition can be represented in an equation, as shown … in ancient greece theatres were
