The spent fuel elements from a fission reactor are much more intensely radioactive than the original fuel elements.
(a)What does this tell you about the products of the fission process in relationship to the belt of stability, Figure?
(b) Given that only two or three neutrons are released per fission event and knowing that the nucleus undergoing fission has a neutronto- proton ratio characteristic of a heavy nucleus, what sorts of decay would you expect to be dominant among the fission products?
Explain why the fluoride ion of the terabutylammonium flouride is more nucleophilic than the fluoride ion of sodium fluoride. Draw reaction-energy diagrams. Define the term, "diastereospecific reaction," and give a representative example.
In group 16 since, the electronegativity decreases so tendency to exhibit -2 oxidation state decreases as we go down the group. why this is so? How electronegativity and oxidation state link with each other.
