undergoing

α

Tritium has a half-life of

12.5

y undergoing beta decay. What fraction of a sample of pure tritium will remain undecayed after

25 y

We are given the following atomic masses:

_{92}^{238} U = 238.05079 u_{2}^{4} He = 4.00260 u

_{90}^{234} Th = 234.04363 u_{1}^{1} H = 1.00783 u

_{91}^{237} Pa = 237.05121 u

Here the symbol Pa is for the element protactinium

(Z = 91)

. (a) Calculate the energy released during the alpha decay of

_{92}^{238} U

. (b) Show that

_{92}^{238} U

can not spontaneously emit a proton.

Text solutionVerified

By definition of half-life, half of the initial sample will remain undecayed after

12.5 y

. In the next

12.5 y

, one-half of these nuclei would have decayed. Hence, one fourth of the sample of the initial pure tritium will remain undecayed.
