alpha decay

occurs mostly in larger nuclei, because nucleus is too large

no matter how many nucleons you add its still too large

single particle (helium nucleus) is ejected from parent nucleus

New cards

If one sixteenth of a radioactive sample is present after 32 minutes, what is the half life?

8 minutes

1/16= (1/2)^4

T= time/ number of half-lives

T=32/4
