Free electrons only
In a copper wire, metallic bonding occurs. Metallic bonding is the type of bonding where electrons are delocalized and free to move throughout the structure, giving metals their unique properties such as conductivity and malleability.
An overwhleming amount of steel is iron; it is therefore metallic.
Elemental iron is metallic. Its low electronegativity allows electrons to move freely between atomic orbits, allowing the conductivity, malleability, and ductility that usually define metals.
The bare copper conductor in non-metallic sheathed cable serves as the grounding conductor. It is designed to safely carry and redirect any electrical faults or leaks to the earth to prevent electric shock or fires. This conductor is uninsulated to facilitate conductivity and grounding capabilities.

In a copper wire, metallic bonding occurs. Metallic bonding is the type of bonding where electrons are delocalized and free to move throughout the structure, giving metals their unique properties such as conductivity and malleability.
In a copper wire, the type of bond present is metallic bonding. Metallic bonding involves the sharing of electrons among a sea of delocalized electrons that move freely throughout the structure, providing metals with their unique properties such as conductivity, malleability, and ductility.
High electrical conductivity, high thermal conductivity, and malleability can be attributed to the delocalized electrons in metallic crystals.
The main three properties of the metals are malleability (you can shape it easily), ductility (you can turn it into a wire) and conductivity (it will carry heat and electricity very well).

Copper is bound by the metallic bond. Simply put, the valence electrons are held in a delocalised bond which is shared throughout the structure.
The flow of current through a wire increases its conductivity and decreases its resistance.
Metal wire has high electrical conductivity.
An ideal wire for electrical conductivity should have low resistance, high conductivity, and be made of a material that is durable and can withstand high temperatures. Additionally, the wire should be flexible and easy to work with for installation purposes.
The reason for this very behaviour of metals is explained by the fact that at random, the free electrons moving in a metallic object (say wire) also collide with the atoms contained in the wire. Due to these collisions, their kinetic energy is wasted to some extent. When the temperature of such a metallic wire is increased, their collisions with the containing atoms become more frequent and ultimately more energy is wasted. This obviously reduce their thermal and electrical conductivity.
