Let's apply the results of Problem 2 to potassium-argon dating frequently used to date sedimentary rocks. Potassium-40 decays by two different paths: electron emission electron capture where conversion to Ca occurs 89.1% of the time, and to Ar 10.9% of the time. The overall half-life for the decay of potassium-40 is 1.248 × 10⁹ years. Estimate the age of sedimentary rocks with an argon-40 to potassium-40 ratio of 1.02 %. 40 10K 19- 40Ca 20 40 19K 40 10 Ar
