- A particular rock is thought to be 234 million years old. If it contains 4.84 mg of 238U, how much 206 Pb should it contain? Assume 238U decays directly to 206PB with a half-life of 4.47 × 109 y.in the stable isotope of Potassium 39K there are 19 electrons, 19 protons and 20 neutrons. The mass of the neutral atom is 38.96371 u. Calculate: Total mass / u Mass defect / u Binding energy / J Binding energy / MeV Mass of the proton = 1.007276 u Mass of the neutron = 1.008665 uA sample of hypothetical element X decays by positron emission and has a half-life of 79 years. How many years are necessary for a sample of this radioisotope to be reduced by 79%? Answer to the nearest year.

(d) What is the maximum possible ki- netic energy (in J) of the a particle emitted during this decay? (Hint: what is the difference between the mass of 23°U and the total mass of 92 231 Th and an a particle?) 90 (e) Whatis the maximum velocity of the emitted a particle?2H is a loosely bound isotope of hydrogen. Calleddeuterium or heavy hydrogen, it is stable but relativelyrare—it is 0.015% of natural hydrogen. Note that deuteriumhas Z = N , which should tend to make it more tightlybound, but both are odd numbers. Calculate BE/A , thebinding energy per nucleon, for 2H and compare it with theapproximate value obtained from the graph in Figure.
- What minimum energy E(min) is needed to remove a neutron from K40 and so convert it to K39? The atomic masses of the two isotopes are 39.964000 and 38.963708 u, respectively. E(min) = ? eVplease write given, reasoning, and stepsUse the uncertainty principle ∆p ∆x > h/2 to calculate the minimum kinetic energy of a nucleon known to be confi ned in 2H. What is the de Broglie wavelength of this nucleon? Is this reasonable?
