A model showing how metallic bonds are formed - the first diagram shows the outer electrons in their atoms, and the second diagram shows that the electrons have become delocalised ...

This is due to the increased positive charge on the metal ion and the increased number of electrons that are delocalised, resulting in stronger bonding.

Based on changes in atomic bond lengths, a similar polyamorphism has now been observed in structurally different metallic glasses. Polyamorphism describes the occurrence of differently ordered ...
