As a materials scientist with a focus on the properties of metals, I can provide a detailed explanation on the electrical conductivity of iron and metals in general.
Electrical conductivity in metals is a complex phenomenon that arises from the nature of the atomic structure and the behavior of electrons within that structure. Iron, being a metal, does indeed conduct electricity, but not because of the individual iron atoms themselves, as the provided content suggests. The ability of iron to conduct electricity is due to the collective behavior of its electrons.
In a solid metal like iron, the atoms are arranged in a lattice structure. Each iron atom contributes some of its valence electrons to a "sea" of electrons that are free to move throughout the entire structure. This is known as the "free electron model" of metallic bonding. The valence electrons that are not tightly bound to any one atom are able to move relatively freely within the lattice. This delocalized electron cloud is what allows metals to conduct electricity.
The movement of these free electrons is not random but is directed by the electric field created by an applied voltage. When a voltage is applied across a piece of iron, the free electrons drift towards the positive terminal, creating an electric current. This movement of electrons is what we perceive as the metal's ability to conduct electricity.
It is important to clarify that the conductivity of iron, or any metal, is not an inherent property of the individual atoms but rather a collective property of the metal as a whole. The individual iron atoms do not conduct electricity on their own; it is the metallic bond that facilitates the movement of electrons across the entire structure.
Furthermore, the conductivity of a metal can be influenced by various factors, including temperature, impurities, and the presence of defects in the lattice structure. As temperature increases, the lattice vibrations (phonons) also increase, which can scatter the electrons and reduce the conductivity. Impurities or defects can also scatter the electrons, impeding their movement and thus reducing the metal's ability to conduct electricity.
In summary, iron conducts electricity not because of the individual iron atoms but due to the collective behavior of the valence electrons that are free to move within the metallic lattice structure. The conductivity is a result of the free electron model of metallic bonding, where these electrons are influenced by an applied electric field to create a current.

Iron conducts electricity because iron atoms are electrical conductors. FALSE: the metal conducts because some electrons are able to move through the metallic lattice structure. The individual atoms can not be considered to conduct.
