1. The problem statement, all variables and given/known data Well one of the questions that I'm not too sure the answer to is what parameter in the nucleus increases as a result of alpha and beta decay. 2. Relevant equations 3. The attempt at a solution Not too sure, I mean atomic number decreases and so does mass number so. But what increases? Theres less nucleons in the nucleus so theres less binding energy but theres also less mass. No idea.
