Atoms of iron (Fe) form metallic bonds with other iron atoms. How are the valence electrons of these atoms rearranged to form the bonds?

In a metallic bond, many valence electrons become delocalized, meaning they can move throughout the structure and are shared among many metal atoms. Iron atoms therefore form bonds through this shared pool of electrons, rather than transferring electrons to or from atoms in the air. The correct choice is “Many valence electrons are shared between the atoms.”
