In the Lewis model - Correct Answer valence electrons are represented as dots, and we draw Lewis electron-dot structures metallic bonding - Correct Answer In the simplest model for metallic bonding—called the electron sea model—all of the atoms in a metal lattice pool their valence electrons. These pooled electrons are no longer localized on a single atom, but delocalized over the entire metal. The positively charged metal atoms are then attracted to the sea of electrons, holding the me...
