How does the electrical conductivity of metals support the electron sea model?

You have a "sea of electrons" and moving electrons through a metal provides an electric current. I assume you can take it from here.

Certainly! The electrical conductivity of metals supports the electron sea model because it explains why metals are such good conductors of electricity.

According to the electron sea model, the atoms in a metal are arranged in a regular pattern, but the outermost valence electrons are loosely held and can freely move throughout the structure. These delocalized electrons form a "sea" of negative charge, surrounding the positively charged metal ions.

When a voltage is applied across a metal, the delocalized electrons can easily move in response to the electric field. This movement of electrons constitutes an electric current. Because the electrons are not bound to specific atoms and can move freely, metals have a high electrical conductivity.

To understand the relationship between electrical conductivity and the electron sea model, you can think about it in this way: if the electrons were tightly bound to their respective atoms and not free to move, they would be less able to carry an electric current. Therefore, the ability of electrons to move freely accounts for the high conductivity observed in metals.
