Regular Chemistry -
Starter- Write the equations for the decay series. Radon -222 decays according to the following decay series. ααβαβ What is the final stable isotope?
Lecture - Nuclear Chemistry
Homework: 4.11 Radioactive 1/2 life and Nuclear Particles and Reactions
Lab-4.7 Nuclear Exploration
Summary - 1) The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed?
2) Pd-100 has a half-life of 3.6 days. If one had 6.02 x 1023 atoms at the start, how many atoms would be present after 20.0 days?
3) Os-182 has a half-life of 21.5 hours. How many grams of a 10.0 gram sample would have decayed after exactly three half-lives?
