Several questions they may not be all answerable but hey :D How do proton and neutrons stay together? If one's got a positive charge and one's got a neutral charge there's nothing holding them together? Once a proton is split from a neutron and/or it's nucleus would you be able to bind them back together? Could you fit a proton onto another nucleus although that would probably make it unstable. What are protons, neutrons and electrons made of? Don't tell me there's smaller building blocks because then what makes them? or does that chain continue infinitly. Do protons, neutrons and electrons have mass or do they only gain mass as an atom? Once an atom is split, where do the protons, neutrons and electrons go? do they wizz off somewhere until they lose all their energy then do they stop moving and just sit there? This question may seem a bit stupid but it'd still be cool if this would happen. For easiness I'm going to label 2 objects, object A and object B. Object A is being pushed down onto Object B whilst being vibrated very fast would Object A start to pass through Object B as the atoms in Object A find gaps in Object B and go down the gaps? or would the bonds prevent this?
