Chapter 24 Review
11. What is radioactivity?
12. How do neutrons affect the stability of an atom’s nucleus?
13. Relate nuclear stability to an atom’s size and its neutron-toproton ratio.
14. Look at Figure 24–7 on page 866 of your textbook. Determine
where on the graph each of the following isotopes would fall:
above, within, or below the band of stability.
a. 14
6 C
b. 107
47 Ag
c. an isotope with an atomic number near 50 and
an n/p ratio of 1.1:1
d. an isotope with an atomic number near 45 and
an n/p ratio of 1.5:1
15. Which radioactive decay processes increase the neutron-toproton ratio of a nucleus? Which process decreases the neutronto-proton ratio?
16. Can carbon dating be used to date accurately the remains of an
animal thought to be 1 million years old? Explain your answer.
17. What is induced transmutation? How does it relate to the
transuranium elements?
18. List three devices that are used to detect and measure radiation.
19. What is the difference between nuclear fusion and nuclear
fission?
20. What effect does radiation have on living cells? What dose is
considered safe?
