Metallic bonding model

Web15 nov. 2015 · Currently, metallic structure and bonding is still described in some university texts as “bonding which involves the delocalization of electrons throughout the metal solid” [ 3] or as “metal ions in a sea of electrons” [ 4 ]. There are discrepancies between the “free electron” model and the principles/calculations in physics [ 5 ]. WebThis article briefly describes the current physical model of metallic structure and bonding. An alternative soft-sphere model of metal structure is introduced. Limitations of the current model are given and properties of metals which can be accounted for by the soft-sphere model are discussed.
