The decay of ⁴⁰K to ⁴⁰Ar can be used to determine the age of very old rocks. What mode of radioactive decay is occurring in the conversion of ⁴⁰K to ⁴⁰Ar?

Question

Quizplus · Accepted Answer

The conversion of potassium-40 (K-40) to argon-40 (Ar-40) occurs through electron capture, a process where an electron from the inner shell is captured by the nucleus, combining with a proton to form a neutron and emitting a neutrino. This process decreases the atomic number by one while keeping the mass number the same, converting potassium to argon.
