Question: The (4n + 3) decay chain begins with 235 U and ends on 207 Pb. (a) How many a decays are there in the chain?

The (4n + 3) decay chain begins with 235U and ends on 207Pb.

(a) How many a decays are there in the chain? 

(b) How many β decays are there? 

(c) Compute the total energy released when one 235U atom decays through the complete chain. 

(d) Assuming no energy escapes, determine the approximate temperature rise of 1 kg of 235U metal over the period of 1 year.
