1. The problem statement, all variables and given/known data 2. The attempt at a solution I thought because they are negatively charged and so they will get attracted to the positive nucleus, and also because they are too small, but they are not acceptable. The answer is that they have a range of energies / they are deviated by orbital electrons/ has small mass . What effect does having a range of energies have? And also small mass? Why.. And why can't I say they are attracted to the nucleus?
