Radioactivity, Half-life, and Nuclear Reactions CH 19 & 20 Review Radioactivity, Half-life, and Nuclear Reactions

Bell Work: 11/8/13 What atomic changes that occur during alpha decay? During beta decay? What are the final products of alpha and beta decay?

Calculate the Amount of the element remaining… The half-life of Unranium-235 is 70 years. If you have 15 grams to start with, how much will you have left in 350 years?

The half-life of Silver-108 is 418 years The half-life of Silver-108 is 418 years. If the sample was 8 grams to begin with, how much would be left after 209 years?

The half-life of Sulfur-35 is 87 days The half-life of Sulfur-35 is 87 days. If the sample was 50 grams to begin with, how much would be left after 1 year?

Practice alpha and beta decay… Barium alpha decay

Chlorine alpha decay

Uranium Beta decay
