This resource is a PowerPoint presentation on nuclear chemistry. Slides Include: decay particles, decay reactions, and real life examples.
This resource is a PowerPoint presentation on radiation. Headings include: radioisotopes, radiation, alpha particle, beta particle, gamma ray, level of penetration, half-life, carbon-14 dating, fission, and fusion.
Atomic Nucleus & Radioactivity
1) State whether or not each of the following isotopes would be radioactive:
- carbon-12 e. europium
b. uranium f. curium
c. iridium g. carbon-14
d. bismuth h. polonium
2) What is the particle emitted when plutonium-244 decays into americium-244?
3) What is the particle emitted when proactinium-231decays into actinium-227?
4) What is the particle emitted when neodymium-144 decays into promethium-144?
5) Write the nuclear equation for the decay of californium-251 with the emission of alpha particles.
6) Write the nuclear equation for the decay of tin-122 with the emission of beta particles.
7) Write the nuclear equation for the decay of radium-228 with the emission of alpha particles.
8) Write the nuclear equation for the decay of astatine-210 with the emission of beta particles.
9) Write the nuclear equation for the fissioning of uranium-235 via neutrons, producing barium–141 & krypton–92.
10) On the back of this sheet, briefly summarize (in table form) the pros & cons of each type of energy source.
