We know that the more electrons there are in the valence shell of an atom, the stronger the London Dispersion Forces are, and therefore, the compound will have a higher melting and boiling points. But now suppose electricity is being conducted through the object. Because it will have a smaller number of valence electrons (those are the charged particles that flow, creating electric current), would it be safe to assume that the London Forces would get weaker, and therefore, the overall sum of intermolecular forces would be less than the original, resulting in lower melting and boiling points? In other words, would it require less energy to break the intermolecular forces on an object that has an current passing through it? Though this up in chemistry class, and posting it in physics forum Pardon my grammar, just woke up EDIT: on the second thought, maybe I should have moved this to Chemistry forum. Sorry.
