Question
If you started with 50 g of Iodine, how much would be left of your original isotope after 2 half-lives? After 3 half-lives? Write out the nuclear decay of your element by alpha decay and by beta decay (choose one isotope of it). Please show work. Thanks!

Amount left = initial amount/2n
no of half lives = n
initial amount = 50g
amount left = 50/22
= 50/4 = 12.5gm
After 3 half lives
no of half lives n = 3
amount left = 50/23
= 50/8 = 6.25gm
53I127 ----->51 Sb123 +2 He4
53I127 -----> 54Xe127 + -1e0 ( beta)
