WebbMetallic objects are formed from pure metals. Sometimes true Metals that are good conductors of electricity are said to be ductile. Never true Drifting valence electrons insulate cations from one another and contribute to the malleability of a metal.

WebbMetallic bonds are not broken when the metal is heated into the melt state. Instead, these bonds are weakened, causing the ordered array of metal ions to lose their definite, rigid structure and become liquid. However, these bonds are completely broken when the metal is heated to its boiling point. Example – Metallic Bonding in Sodium cure for shin splintsWebbWhile ionic bonds join metals to nonmetals, and covalent bonds join nonmetals to nonmetals, metallic bonds are responsible for the bonding between metal atoms. In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.
