Metallic Bonding and the Electron Sea Model, Electrical Conductivity – Basic Introduction

This chemistry video tutorial provides a basic introduction into metallic bonding and the electron sea model. The valence electrons in the metal are delocalized – they are free to move around stationary metal cations. This explains the electrical conductivity of metals. A substance with free-flowing charge can conduct an electric current. The charge carrier in metals are valence electrons. The core electrons in metals atoms are localized – they are bound to their respective atoms and are not free to move from one metal atom to another.
