A decay sequence for a radioactive atom of radon 219 to stable lead 207 atom is as shown below. (i.) What particle is emitted when 21183Bi is decays? (ii.) What happens within the nucleus to cause this decay? (iii) The half-life of 21986Pb is 4.0s. At time t = 20 s, what fraction of radon atoms present at time t = 0, will be undecayed?
