1 Isotopes 1. Carbon-12 and Carbon-14 have a different number of A. Protons B. Neutrons C. Both D. Neither

2

3 2. Which statement is true about an isotope s half life? Radioactive Isotopes A. Isotopes of the same element will have the same half life. B. The longer a half life, the less stable an isotope is. C. An isotope s half life cannot be changed. D. All of the above.

4

5 3. When an isotope undergoes fission, A. Energy is released. B. Another isotope is produced. C. Particles are released. D. All of the above.

6

7 curies of Strontium-89 was released from the Hanford plant. It has a half life of 50 days. How many days later will it be after 2 half-lives have elapsed? A. 100 days B. 175 days C. 350 days D. 700 days E days Radioactive Decay

8 curies of Strontium-89 was released from the Hanford plant. It has a half life of 50 days. How many curies of Sr-89 will be left after 100 days? A. 0 curies B. 100 curies C. 175 curies D. 350 curies E. 700 curies Radioactive Decay

9

10 6. When a neutron decomposes into a proton and an emitted electron which type of radiation is occurring? A. Alpha B. Beta C. Gamma D. Positron

11 7. A particle emitted during nuclear decay that consists of 2 protons and 2 neutrons (a helium nucleus) is a A. Alpha particle B. Beta particle C. Gamma ray D. Positron

12 8. Which of the following types of radioactive decay will change the isotope from one element to another? A. Alpha B. Beta C. Gamma D. Both A and B E. A, B and C

13 9. Which of the following types of radioactive decay will decrease the mass of the isotope? A. Alpha B. Beta C. Gamma D. Both A and B E. A, B and C

14 Alpha decay decreases the atomic number by 2, because the alpha particle includes two protons. The mass decreases by 4 since the particle also contains to neutrons. Beta-plus decay decreases the atomic number by one since a proton is split into a neutron and a positron. The mass does not change since the particle released does not contain significant mass.

15 Beta minus decay INCREASES the atomic number by one since a neutron is split into a proton and an electron. The mass does not change since the electron that is released does not have significant mass. Gamma radiation does not change the atomic number or the mass of an atom.

32 Uranium Reserves

33 21. Different isotopes have A. Different atomic numbers B. Different masses C. Both A and B D. Neither A nor B

34 Carbon-14 is incorporated into organic molecules in the same way that carbon- 12 is. This is why carbon-14 dating can be used to date organic materials by determining what percentage of carbon-14 remains.
