The model of sea electrons helps explain?

The model of sea electrons helps explain the behavior of metals and their conductivity by positing that a "sea" of delocalized electrons surrounds positively charged metal ions. This sea allows electrons to flow freely throughout the metal lattice, facilitating electrical conductivity and thermal conductivity. Additionally, it accounts for the malleability and ductility of metals, as the electrons can move and shift without breaking the metallic bonds. Overall, the sea of electrons is crucial for understanding the unique properties of metallic substances.
