==Key Stage 4==
===Meaning===
A '''giant metallic structure''' is a group of [[metal]] [[atom]]s held together by [[Metallic Bond|metallic bonds]].
===About Giant Metallic Structures===
: In '''giant metallic structure''' the [[metal]] [[atom]]s are held together as a [[lattice]] of [[Positive Ion|positive ions]] surrounded by a sea of [[Delocalised Electrons|delocalised electron]]s.
: In a [[pure]] [[element]] the [[atom]]s are arranged in a regular [[lattice]].
: When there is a [[mixture]] of [[metal]] [[element]]s it is called an [[alloy]] and the different [[atom]]s change the pattern in the [[lattice]].
: A small number of different [[metal]] [[atom]]s added to a [[material]] can change the [[Physical Property|physical properties]] and [[Chemical Property|chemical properties]] of the [[material]].
===Bulk Properties===
: In their [[solid]] [[State of Matter|state]] '''giant metallic structures''' are good [[Electrical Conductor|electrical conductors]] because it contains [[Delocalised Electron|delocalised electrons]].
: Most '''ionic compounds''' are [[soluble]] in [[water]].
: When [[dissolve]]d in [[solution]] '''ionic compounds''' are good [[Electrical Conductor|electrical conductors]] because the [[Charge|electrically charged]] [[ion]]s are free to move.
: '''Ionic compounds''' form [[Giant Ionic Structure|giant ionic structures]] which have high [[Melting Point|melting points]] due to the strong [[Electrostatic Force|electrostatic force]] between the [[ion]]s.
