Stream of thoughts on atoms

  1. Jun 22, 2008 #1
    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?

    Strong nuclear force

    One can make nuclei on an artificial way yes

    You first ask a question what they are made of, then you don't wanna hear the answer??\

    The proton and neutron are made up of quarks, the quarks - in their turn - is thought as beeing fundamental particles, i.e not made up by anything else than by themselves. But that is what physics today tells us, sience is an ongoing process.

    Yes they have mass by themselves, and this answer you could just use google to find it..

    They are usally end up beeing caught by some other atom/ion or nuclei.

    It depends on what A and B are, what energies you are discussing and so on.

    Something similar to this does indeed happen in certain materials, but probably not the way in which you imagine it. Look up a technique known as Ultrasonic Welding, where applied ultrasonic vibrations break the bonds locally near the interface between the two objects, causing them to essentially melt and flow into each other. Without the applied vibrations, it is still possible to achieve what is known as a Cold Weld (especially at elevated temperatures - and a higher temperature is really just faster vibrating atoms), through the process of solid state diffusion, but here too, interatomic bonds must be broken and reformed as atoms of A and B migrate past each other. There is no way to achieve what you describe without breaking the A-A and B-B bonds.

    Thanks for answering them, for the resource and for the explanation on Ultrasonic Welding. Gonna go look it up :)
