Ions made up of more than one ion
Oxyanion
Polyatomic ion composed of an element, usually non-metal, bonded to more than one atom
Electron sea model
States all metal ions in a metallic state contribute their valence electrons to form a “sea”
Delocalized electrons
Atoms in a bond that easily move
Metallic bond
Attraction if a metallic cation for delocalized electrons
Alloy
Mixture of elements that have metallic properties
Substitutional alloys
Original metal atoms replaced with other metal atoms
Interstitial alloys
Formed with small holes in a metallic crystal with other smaller atoms ex: carbon steel
Chemical bond
Force that holds two atoms together
