![Consider the decay scheme RaE → RaF ↳ RaG (stable). A freshly purified
sample of RaE weighs 5 × 10-¹0 g at time t = 0. If the sample is undisturbed,
calculate the time at which the greatest number of atoms of RaF will be
present and find this number. Derive any necessary formula [Half life of RaE
(30Bi) = 5.0 days; Half life of RaF (1ºPo) = 138 days]
