A metallic bond is type of chemical bond in which metal atoms are held together as a group of positive ions surrounded by a sea of delocalised electrons.

Metallic bonds happen between metal atoms. This can be between atoms of the same element or different metal elements (an alloy).

In metallic bonds the atoms form a lattice of positive ions surrounded by a sea of delocalised electrons.


The outer shells of the Magnesium atoms overlap allowing the two electrons in each outer shell to move freely between atoms.	The outer shells of the Aluminium atoms overlap allowing the three electrons in each outer shell to move freely between atoms.
