a) For a nucleus of , estimate very roughly how many nucleons would be at the surface.
b) If the binding energy of an interior nucleon due to the internucleon attraction were and if all nucleon were are tightly bound, the total binding energy would be . Taking into account the different binding of surface nucleons, roughly what would be the total binding energy?
Two deuterons can fuse to form different products. Although not the most probable outcome, one possibility is helium-4 plus a gamma particle. Calculate the net energy released in this process.
What fraction of space is actually occupied by ironnuclei in a "solid" piece of iron? (The density of ironis ).
Question:In Section 11.2, it is said that iron and nickel represent maximum stability. Chemistry emphasizes that helium is the most stable element? How can these claims be reconciled?
Polonium- 207 may undergo three kinds of undergo radioactive decay: and electron capture but it does not decay. Given its position relative to the curve of stability, explain why this is not unexpected.
