Nuclear Chemistry Worksheet Answers N 16 is unstable and radioactive because its neutron proton ratio is too high c Nuclear reactions often produce large amounts of energy because small amounts of mass are converted into energy see Einstein s famous equation e mc 2
Construct nuclear equations for the spontaneous decay of radioactive nuclides Writing Nuclear Equations Use Table N When elements undergo radioactive decay they change from one element to another This happens by losing high energy alpha or beta particles or Use Reference Table on side to assist you in answering the following questions 1 How long does it take a lOO OOg sample of As 81 to decay to 6 25g 2 How long does it take a 180g sample of Au 198 to decay to 1 8 its original mass 3 What percent of a sample of As 81 remains un decayed after 43 2 seconds 4
