024 - Metallic Solids
In this video Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance, malleability, ductility, and the ability to form alloys. Alloys can be substitutional or interstitial in nature and can change the chemistry of the metal.
