===Meaning===
A [[Metal]] is a a [[material]] that is a good [[Electrical Conductor|conductor]] of [[electricity]] and a good [[Thermal Conductor|conductor]] of [[thermal energy]].
===About Metals===
: [[Metal]]s are found on the left hand side of the [[Periodic Table]]

: [[Metal]]s lose [[electron]]s to form [[Positive Ion|positive ions]] in [[compound]]s with [[non-metal]]s.
: [[Metal]]s form [[Hydroxide]]s when they [[Chemical Reaction|react]] with [[water]].
: [[Metal]] [[element]]s form [[Metallic Bond|metallic bonds]] in which [[Positive Ion|positive ions]] are surrounded by a sea of [[Delocalised Electron|delocalised electrons]].
: A [[metal]] made of more than one [[metal]] [[element]] is called an [[alloy]].
: [[Metal]]s make good [[Electrical Conductor|electrical]] and [[Thermal Conductor|thermal]] [[conductor]]s because the [[Delocalised Electron|delocalised electrons]] are free to move around the [[material]].
