1. An alpha particle is fired at a sheet of gold with a kinetic energy of 4.62E-13 joules. Knowing that each gold nucleus has 79 protons, about how close will the alphas come to the nucleus?
2. If the binding-energy-per-nucleon for an alpha particle is 61.0 MeV, what is the total binding energy of the alpha? Give you answer is MeV.
3. Radioactive phorsporous-32 has been used to study bone metabolism and for the treatment of blood diseases. What is the activity of a sample of 12.2x10^16 atoms if it has a half-life of 109 days?© BrainMass Inc. brainmass.com December 24, 2021, 4:42 pm ad1c9bdddf
I have given the answer in the adjoining pdf file.
<br>I like to mention that the question 2 ...
The binding energy per nucleon for an alpha particle is examined. The radioactive phosphorus-32 for treatment blood diseases are given.
