A '''metallic bond''' is type of [[Chemical Bond|chemical bond]] in which [[metal]] [[elementatom]]s are held together as a group of [[Positive Ion|positive ions]] surrounded by a sea of [[Delocalised Electrons|delocalised electrons]]. ===About Metallic Bonds===: '''Metallic bonds''' happen between [[metal]] [[atom]]s. This can be between [[atom]]s of the same [[element]] or different [[metal]] [[element]]s (an [[alloy]]).: In '''metallic bonds''' the [[atom]]s form a [[lattice]] of [[Positive Ion|positive ions]] surrounded by a sea of [[Delocalised Electrons|delocalised electrons]]. ===Examples==={| class="wikitable"|-|[[File:MagnesiumMetallicBond.png|center|300px]]|[[File:AluminiumMetallicBond.png|center|300px]]|-| style="height:20px; width:200px; text-align:center;" |The [[Outer Shell|outer shells]] of the [[Magnesium]] [[atom]]s overlap allowing the two [[electron]]s in each [[Outer Shell|outer shell]] to move freely between [[atom]]s.| style="height:20px; width:200px; text-align:center;" |The [[Outer Shell|outer shells]] of the [[Aluminium]] [[atom]]s overlap allowing the three [[electron]]s in each [[Outer Shell|outer shell]] to move freely between [[atom]]s.|}
