Metallic Crystals | Introduction to Chemistry

Metallic Bonding. Loosely bound and mobile electrons surround the positive nuclei of metal atoms. Understood as the sharing of “free” electrons among a lattice of positively charged ions (ions), metallic bonding is sometimes compared to the bonding of molten salts; however, this simplistic view holds true for very few metals.
