Lab: Half-Life
Question 1 • Foothill-B Period-Chemistry-26/27B
Suppose you could watch radioactive atoms decay. It would probably get quite boring as time went by. Why? Check all that apply.
Answer
A
The initial decay rate is very fast, but the decay rate decreases over time.
B
Due to randomness, the last couple of radioactive atoms may take a long time before they become nonradioactive.
C
The pattern becomes very predictable.
D
Only a few radioactive nuclei are left to decay, so fewer and fewer atoms decay.
E
The rate of the decay decreases with each half-life cycle.
F
The probability that an atom will decay is reduced with each half-life cycle.
