CHM 102 Radioactivity Objective Question
Take CBT

Question

How does the amount of a radioactive isotope (e.g., 1 g vs. 1000 g of 24Na) affect its half-life?
Options
A Larger amounts have a longer half-life.
B Smaller amounts have a shorter half-life.
C The half-life is independent of the amount of isotope.
Correct Answer
D The half-life increases proportionally with the amount.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 9 states: 'The value of half-life is independent of the amount of isotope (i.e. regardless of if we have 1 g or 1000 g of 24Na the half-life is still 15 hrs)'.

Hint

Look for the statement on page 9 about the independence of half-life.
