🤓 Based on our data, we think this question is relevant for Professor Beck's class at OHIO.
Recall that radioactive/nuclear decay of isotopes follows first-order kinetics, and the integrated rate law for first-order reactions is:
Step 1. Calculate for the decay constant (k):
half-life = 3.1 min:
The isotope 208Tl undergoes β decay with a half-life of 3.1 min.
(b) How long will it take for 99.0% of a sample of pure 208Tl to decay?
