A neutron decays into a proton by one of the constituent down quarks decaying into an up quark, emitting a W boson, which decays into an electron and anti-neutrino. Edit Report an issue 30 seconds. Stronitium-84 is composed of 38 protons, 46 neutrons, and 38 electrons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the, A property closely related to an atoms mass number is its, Since an elements isotopes have different atomic masses, scientists may also determine the.
