Please Explain! Determine whether the following nuclides will undergo alpha decay a) 214Po b) 199Hg (mass=198.968262U)

Expert Solution

The prior posting does not answer the question and I do not have time to work all of this out at the present, but here is the proper method to determine if the given nuclides will spontaneously undergo alpha decay. In alpha decay, you start with a Parent nuclide on the left side of the reaction arrow (like in chemistry), and end up on the right side with an Alpha plus a Daughter nuclide. You will need to look up the masses (in amu or u units) for each Parent, Daughter, and the Alpha from whatever sources you have available; sometimes they are given in an appendix in the back of your textbook. Here is the condition that must be true in order for alpha decay to occur spontaneously: ( Mass of Parent - Mass of Alpha - Mass of Daughter ) > 0 . If that quantity in parens is positive, then alpha decay is possible . If that quantity in parens is negative, then alpha decay is NOT possible !! hope this helps !!

Which type of nuclear decay is the following radioactive isotope likely to undergo? All known stable isotopes are shown on the graph. The points form what is know as the "belt of stability". If a radioactive isotope is above the belt of stability, think about what type of decay would decrease its N/Z ratio. If an unstable isotope is below the belt of stability, think about what type of decay would increase its N/Z ratio. If a radioactive isotope is...

Predict whether each of the following nuclides is stable or unstable (radioactive). If the nuclide is unstable, predict the type of radioactivity you would expect it to exhibit. I have the answers but don't understand part of them. (a) 20^11_Na Stable (I understand why, the mass is too light to be stable.) But why are the types of radioactivity electron capture and positron production? Why not alpha decay too? Those three are all used when the nucleus is too light, so...

For the question, please explain and provide details During B-cell activation some activated B-cells undergo differentiation into antibody secreting plasma cells outside of the germinal center and therefore never go through the germinal center responses. Other activated B-cells will return to the follicle forming a germinal center and undergo processes that alter the antibody that will be produced. Describe the germinal center responses. Why are these responses important (hint: what is different about the antibody produced)? Why are T cells...
