Your quiz on Unit 9 will be on Thursday, May31 and
cover material from Chapter 19 of the textbook and your packet. Quiz questions
will target the following objectives.
You should be able to ...
- Radioactive Decay: To
interpret isotope symbols in order to describe the components of a
nucleus, to describe the various decay particles and decay processes,
and to use such understandings to predict how a nucleus would decay.
Chapter 19.1-2; Chapter
19.1-2 Reading Guide (pp. 1-2); Radioactive Decay (pp. 3-4)
- Balancing Nuclear Equations: To use charge conservation and mass conservation to balance a nuclear equation for a decay, bombardment, or fusion process.
Resources: Radioactive Decay Series (p. 5); Nuclear Bombardment (p. 6); Stellar Nucleosynthesis (pp. 7-8)
- Half Life and Radioactive Decay Rates: To
use the concept of half-life to predict the amount of a radioactive
sample remaining after a specified time or to determine the time for a
sample to diminished to a specified amount.
Chapter 19.3-4; Chapter
19.3-4 Reading Guide (pp. 11-12); Half-Life and Radioactive Decay (pp. 13-14)
- Binding Energy: To
understand the concept of binding energy and Einstein's equation to
predict the stability of a nucleus based on mass defect values.
Resources: Binding Energy (pp. 9-10)
