The radioactive Isotope 28P decays by positron emission. If the mass of a sample of phosphorus-28 decays from 79.2 micrograms to 9.90 micrograms in 0.840 seconds, what is the half-life of phosphorus-28? Half-life = seconds use the keferences to access important values in the for the p The half-life of the radioactive isotope thorium-230 is 8.00 x 10¹ years. How long will it take for the mass of a sample of thorium-230 to decay from 88.8 micrograms to 22.2 micrograms? years The radioactive isotope carbon-14 is used for radiocarbon dating. The half-life of carbon-14 is 5.730 × 10³ years. A wooden artifact in a museum has a 14C count that is 1.56 x 10-2 times that found in living organisms. Estimate the age of the artifact. Age = years
