Homework Statement


the variation of nuclear binding energy per nucelon of nuclei P , Q , R and S are shown.
Which process most likely to occur?

the ans is P to Q ... why not S to R ?

both
P to Q and S to R involve formation of unstable nucleus to more stable nucleus....

1. Radioactive decay is the process fission. What will this do with the number of nucleons?
Your answer to this should tell you which way any likely reaction would go, either:
  • S ##\rightarrow## R and Q ##\rightarrow## P.
  • S ##\leftarrow## R and Q ##\leftarrow## P.
2. To achieve a more stable atom, that is a resulting atom with a higher binding energy, which way will the respective reactions go?

As soon as you know the answer to these two conditions, only one possible option will remain :)...

I think you need to read my previous reply a bit more careful ;)..

Both 1. and 2. Has to be fulfilled.. Also, your statement about stability, are both correct? Remember, higher binding energy ##\rightarrow## more stable.

Do the problem actually mentions "radioactive decay"?
How is a decay in which the number of nucleons increases?
