Homework Statement
I have my GCSE A level Board exam in three days and i am a bit confused about this topic, there is a usual question where they give you data about the energy released when a nucleus decays, and they ask you to suggest with a reason which one has a greater binding energy, or greater decays constant.
question 1:
the beta decay of Strontium produces Yittrium and releases 5.5MeV of energy, suggest which nucleus (Sr or Y) has the greater binding enrgy.
question 2:
two isotopes of Radium (224 and 226) undergo alpha-particle decay, the energy of their a-particles is 5.68MeV and 4.78MeV respectively, suggest which of the two isotopes has the greater decay constant.
so could anyone tell me exactly how to go about answering these questions, and pls don't give me a link to a wikipedia page, i just need a quick clarification.
thanks alot.
