Radioisotope: isotope that is radioactive Isotope: different versions of the same element. They have the same # of protons, different # neutrons Radioisotope: isotope that is radioactive Stability: neutron to proton ratio is 1 (for elements H through K) 1.5 (for elements Ca through Bi) Half Life Time it takes for half of the atoms in a sample to decay
