you know the way the moon goes around the earth but the earth also goes around the moon, its just the mass difference means that middle point is closer to earth than it is to the moon so its seems like that the moon just goes around the earth.
is it the same with electrons and protons?obviously the heavier atoms are a little complicated but lets say for a hydrogen atom that has no neutrons/1 neutron/more than one? does the nucleus and the electron circle each other? with the centre point closer to the nucleus?
