Question

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

A few valence electrons are shared between the atoms.
Many valence electrons are shared between the atoms.
Electrons are transferred from the iron atoms to atoms in the air.
Electrons are transferred to the iron atoms from atoms in the air.

Answer 1

Many valence electrons are shared between the atoms.

In metallic bonding the valence electrons become delocalized over the entire metal lattice (an "electron sea") and are shared by many atoms, which holds the positive metal ions together and gives metals conductivity and malleability.
