Question

22. Define the term B-decay. What happens to the mass number and atomic number when a B-particle is emitted
by a nucleus ?​

Answer 1

Answer:

In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. ... By this process, unstable atoms obtain a more stable ratio of protons to neutrons.
