Please help with the following:
32P is an unstable isotope of phosphorus that has a half-life of 14.29 days. Atoms of this isotope undergo beta decay in which a neutron decays into a proton and an electron.
a) Please describe the mass and atomic number of the element that results.
b) How long would a sample contaiinng this isotope decay to 1/32 of its radioactivitiy?
