Starting with U-235 and ending with Pb-207, propose the decay
chain (by writing out a series of nuclear reactions). How many
alpha decays and how many beta decays must occur?

Very Important Rule - The first step of your decay
chain MUST be a beta decay. This will make this chain not
natural, however, the point of this activity is for you to show off
your nuclear skills
Also, people forget to answer the questions so be sure
to have a HUGE box that says "I used _____ alphas and _____ betas!"
after your series of nuclear equations!
