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...

Dislocations - a defect in the crystalline lattice. Dislocations move within a structure when stress is applied Pinning - inhibits the dislocation from moving within the structure resulting in the metal becoming stronger and more brittle. Precipitates - small atoms that fit within the vacant spaces between base metal atoms Entanglements - grains of a structure becoming stretched out. Created by cold working Tensile strength - A measure of how much stress from pulling, or tension, a materia...
