Name __________________

Type of emission:

Alpha or Beta decay? Why

Evidence

1. Uranium-234 To Thorium-230

Alpha Decay

Mass went down by 4

2. Thorium-230 to Radium-226 3. Radium-226 to Radon-222 4. Radon-222 to Polonium-218 5. Polonium-218 to Lead-214 6. Lead-214 to Bismuth214 7. Bismuth-214 to Polonium-214 8. Polonium-214 to Lead-210 9. Lead-210 to Bismuth210 10. Bismuth-210 to Polonium-210 11. Polonium-210 to Lead-206

Integrated Science 2014 Alpha Decay: Alpha Particle: ___protons & ___ neutrons Atomic number down by __, Mass down by _ Example: Radon-222 decay

1. Polonium-218 2. Polonium-214 3. Polonium-210 4. Radium-224 5. Radium-220 6. Radon-220 7. Radon-219 Beta Decay: Electron emission. Neutron changed to a __________, so atomic number up by ____ 1. Lead-210 2. Lead-214 3. Bismuth-210 4. Bismuth-212 5. Bismuth-214
