What interatomic bonding occurs in metals?

Bulk metals are characterized by #"metallic bonding...."#


....#"metallic bonding...."# which features an infinite array of close-packed metal atoms, EACH of which contribute one or more (or several) valence electrons, the which are delocalized over the entire metallic structure. And this gives rise to the common description of metallic bonding, #"positive ions in a sea of electrons."#

And metallic bonding results in a plastic, deformable structure, in which the individual metal atoms can move with respect to each other, without disrupting the metallic bond. And as a result, metals are typically (i) malleable, i.e. they can be beaten out into a sheet, and (ii) ductile, they can be drawn out into a wire. And some few metals (which one?) are actually a liquidus...

The valence electrons are thus delocalized over the entire lattice, and such interaction, featuring free electrons, is also responsible for (iii) generally good electrical conductivities, and (iv) good thermal conductivities.

A very strong attraction between positive metal ions.


A metallic bond is a VERY strong attraction between positive metal ions that are surrounded by a 'sea' of delocalised electrons.
