6. One form of nuclcar radiation, beta decay, occurs when a neutron changes into a proton, an clectron, and a neutral particle called an antineutrino: n → p+ + e¯ +Ve, where ve is the symbol for an antincutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the clectron and neutrino are ejected from the nucleus. The ejected electron is called a beta particle. One nucleus that exhibits beta decay is the isotope of hydrogen ³H, called tritium, whose nucleus consists of one proton (making it hydrogen) and two neutrons (giving tritium an atomic mass m = 3u). Tritium is radioactive, and it decays to helium: 3H → *He + e¯+Ve• (a) Is charge conserved in the beta decay process? Explain. (b) Why is the final product a helium atom? Explain. (c) The nuclei of both 3H and 3He have radii of 1.5 x 10 15 speed must the electron be ejected if it is to escape from the nucleus and not fall back? m. With what minimum
