"Sea" of electrons in metals Is it a "floating" sea of electrons in metals? meaning they are not restricted to a spot relative to the atoms, but they just "float" around as long as it's in the metal, and the charge is almost perfectly level throughout the metal. (I doubt it would be absolutly entropicly level) Arn't electrons pulled by gravity? So a metal pole being held up vertically would stay there because the atoms are "locked" into place with relation to eachother, but the floating electrons are not, so would they fall to the bottom edge of the pole? This effect might be very very small because the entropy of the charge forces would be much stronger then gravity.
