Main Question or Discussion Point
Also relate to its reactivty? Because I heard that the easier something loses valence e-, the more conductive it is. This also applies to reactivity, because if an atom has its outermost shell filled by only 7 electrons, it would be reactive, and react by losing the valence electron to another atom. So if we have a whole piece of matter, lets say Aluminum, which has 3 valence electrons, all the atoms will share valence electrons readily because they are reactive, but current depends on how well electrons pass through the matter. I dont understand.
