  1. Aim: How are nuclear reactions different from ordinary chemical reactions? Do Now: What topics will be on tomorrow’s test?: • Stability • Alpha decay • Beta decay • Positron emission • Nuclear equations • Natural transmutation • Artificial transmutation • Fission and fusion • Half-life • Uses and dangers of radioisotopes • Regents preparation

  2. Aim: How are nuclear reactions different from ordinary chemical reactions? Essential questions • How many half-lives of radon-222 have passed in 11.46 days? • If 5.2 x 10-8 g of radon-222 remain in a sealed box after 11.46 days, how much was present in the box initially? • Explain how carbon-14 is used to determine the age of an object. • Why is potassium-40 used to date ancient rocks and minerals? • Why is uranium-235 considered to be a greater health threat than radon-222? • Identify three practical applications of nuclear chemistry.
