What sort of bonds does aluminum form?
Aluminum metal forms
Aluminum is non-molecular, and each aluminum nucleus contributes a few of its valence electrons to the metallic lattice. The result is metallic bonding; which gives rise to the usual metallic properties, e.g. malleability, ductility, conductivity towards heat and electricity.
As regards chemical bonds with other elements, aluminum has a rich inorganic chemistry, and a rich organic chemistry.
