Based on their relative positions in the periodic table, which might you expect to be a stronger oxidizing agent, chlorine or fluorine? Why?
A) Chlorine should behave as a stronger oxidizing agent because it has a smaller effective nuclear charge in its outermost shell.
B) Fluorine should behave as a stronger oxidizing agent because it has a smaller effective nuclear charge in its outermost shell.
C) Chlorine should behave as a stronger oxidizing agent because it has a greater effective nuclear charge in its outermost shell.
D) Fluorine should behave as a stronger oxidizing agent because it has a greater effective nuclear charge in its outermost shell.
Question 2
What property of half-lives makes radioactive material so problematic?
A) There is no known way to shorten a half-life.
B) Radioactivity is limited by the natural decay-time to stable isotopes.
C) All half-lives are long.
D) There is no known way to measure half-lives with any accuracy.
E) both A and B
