In terms of non-metals, the electrons are held tightly by the nucleus. Therefore nonmetals are very unwilling to give their electrons away. Nonmetals don't donate electrons as easily as metals, so society and chemists from the early ages distinguished between metals and nonmetals, Regards, Mike
Any external influence which moves one of them will cause a repulsion of other electrons which propagates, domino fashion through the conductor. Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.
