Metallic bonding, an Uncommon card

The card carries these facts from its Wikipedia article.

• Metal atoms lose their valence electrons to a large, delocalized orbital, which leaves the nucleus, and other electrons that are closer to the nucleus, as positively charged cations.
• The ions form a crystal lattice as they are held together by the negative charge of the delocalized orbital.
• It may be described as the sharing of free electrons among a structure of positively charged ions, and as a more delocalized version of covalent bonding.
