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.

Metallic lattices do not contain fixed numbers of atoms. This means that the chemical formula used for a metal is simply the symbol for the element. For example, the formula for iron is Fe, even ...

They have proposed the underlying origins of fragility in metallic glass (MG) from an electronic structure standpoint ... to the formation of covalent-like bonding between Al-Al interactions ...
