Name: _________ANSWER KEY ______________________ Date: ______________________________ Period: ________ Nuclear Chemistry – Alpha, Beta, and Gamma Decay Practice Identify the following examples as alpha, beta, or gamma decay. 1. U gamma He + 2. Tc  gamma e + 3. Pt  _beta__ Th Ru Os + _alpha_ 4. Tl  _beta__ 5. I 6. Br  He _alpha_ Tl + ɣ ɣ + I Kr + e Alpha Decay: Write the alpha decay equations for the following nuclides. Example: 7. Lr Po   He + He + Pb Md 9. Au  He + Ir 8. Pa  He + Ac Fr  10. He + At Beta Decay: Write the beta decay equations for the following nuclides. Example: 11. 12. Na  Au  C N+ O+ e Hg + e Am  13. e 14. Sr  Cm + e Y+ e Balancing Decay Reactions: Fill in the blank in each of the following decay reactions with the correct decay particle or decayed nucleus that will balance the reaction, also state whether it is alpha or beta decay 15. 16. W S He + + Hf Cl is an example of _alpha_ decay. is an example of _beta__ decay. 17. Pb  He + Hg is an example of _alpha_ decay. 18. Bi  He + Tl is an example of _alpha_ decay. 19. Po  e + N is an example of _beta__ decay. 20. W  e + Ni is an example of _beta__ decay.
