Question

Quizplus · Accepted Answer

Electron capture by a nucleus results in the conversion of a proton into a neutron, thereby decreasing the atomic number by one while keeping the mass number the same. Tin (Sn) has an atomic number of 50, so the decay of tin-110 by electron capture would produce an element with an atomic number of 49, which is indium (In), making the correct answer indium-110 (C).
