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.
A B C or D

Answer 1

B — Many valence electrons are shared between the atoms.

In metallic bonding the valence electrons become delocalized and form an "electron sea" that surrounds the positive metal ions, holding the lattice together.
