Explain the association between conductivity and the metallic bond. - Leaving Cert Engineering - Question 1 - 2014

Metallic bonding occurs when cations are surrounded by a 'sea' of delocalized electrons. These electrons are not bound to any specific atom, which allows them to move freely throughout the metallic structure. This movement of electrons is crucial for electrical conductivity.

In metals, this 'sea' of electrons facilitates the flow of electric current. When an electric field is applied, these free electrons can easily drift toward the positive charge, thus conducting electricity efficiently.

Moreover, the presence of mobile electrons contributes to the malleability and ductility of metals. The ability of metal atoms to shift positions without breaking the metallic bond allows metals to be shaped and stretched without losing their conductivity.
