A radioactive isotope of mercury, 197Hg, decays to gold, 197Au, with a disintegration constant of 0.0108 h-1. (a) Calculate the half-life of the 197Hg.What fraction of a sample will remain at the end of (b) three half-lives and (c) 10.0 days?

Measurements of the radioactivity of a certain isotope tell you that the decay rate decreases from 8265 decays per minute to 3055 decays per minute over a period of 5.00 days. What is the half-life T1/2 1/2 of this isotope? Express your answer numerically, in days, to three significant figures.

Radioactive element AA can decay to either element BB or element CC.The decay depends on chance, but the ratio of the resulting number of BB atoms to the resulting number of CC atoms is always 2/1.The decay has a half-life of 8.00 days.We start with a sample of pure AA. How long must we wait until the number of CC atoms is 1.50 times the number of AAatoms?
