At STP, which substance has metallic bonding?
Anuta_ua [19.1K]
Silver.  For the most part only metals can have metallic bonding.  Ammonium chloride has ionic bonding (poly-atomic cation + nonmetal=ionic bonding), iodine is a diatomic element so it will form a covalent bond with itself, and barium oxide has ionic bonding (metal+nonmetal or metal+poly-atomic anion=ionic bonding).

I hope this helps.  Let me know in the comments if anything is unclear.
