The nature of metallic bonding accounts for many of the physical properties of metals, such as conductivity and malleability.

Because their electrons are mobile, metallic solids are good conductors of heat and electricity. Metallic solids also tend to be malleable and ductile due to the ability of the metal nuclei to move past each other without disrupting the bonding.

There are two main types of alloys: interstitial alloys, which form between atoms of different radii, and substitutional alloys, which form between atoms of similar radii. In this video, we'll learn how to represent the different types of alloys using particulate models.
