Which statement best describes the effect of low ionization energies and low electronegativities on metallic bonding?

Low ionization energy means metal atoms can give up their valence electrons easily, while low electronegativity means they do not attract those electrons strongly. As a result, the valence electrons spread throughout the metal lattice rather than remaining attached to individual atoms. This is why choice A, “The valence electrons are easily delocalized,” best describes metallic bonding.
