Consider a sample of a pure beta-active material and select the correct information(s) — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Beta decay shares energy between the beta particle and an antineutrino, resulting in a continuous energy spectrum (varying kinetic energies) for the beta particles. The mass number does not change during beta decay, so the product is an isobar of the parent. Beta particles do not exist within the nucleus; they are created upon decay. Antineutrinos have near-zero mass but carry non-zero momentum. Therefore, correct answer is A,D.
