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.

Option (b) is the correct answer.

Explanation:

Metallic bonds are defined as the bonds formed due to attraction between free electrons of a metal with another metal.

It is known that iron is a transition metal whose electronic configuration is .

So, in order to attain stability when an iron atom bonds with another iron atom then it requires more number of electrons in order to completely fill its d-shell.

Hence, we can conclude that valence electrons of iron (Fe) atoms will rearrange to form the bonds as many valence electrons are shared between the atoms.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
