Can someone tell me the role of 'free' electrons in a metallic bond?
i've answered below here... am i right? and if there is detailed explanation?
my answer : Solid metal are therefore visualized as consisting on positive-ion cores (atoms without their valence electrons) and of valence electron dispersed in the form of and electron cloud that covers a large extend of space. The valence electrons are weakly bonded to the positive-ion cores and readily move in the metal crystal; they are generally referred to as free electrons. Free or delocalized electrons may also exist in some crystals that primarilly contain covalent or ionic bonds; for instance, graphite.
