==Key Stage 4==
===Meaning===
[[Metal Ion]]s are [[Positive Ion|positive ions]] found in [[Ionic Compound|ionic compound]]s and [[Giant Metallic Structure|giant metallic structures]].
===About Metal Ions===
: '''Metal ions''' are formed when [[metal]] [[element]]s lose their [[electron]]s to form [[Positive Ion|positive ions]].
The [[charge]] on a '''metal ion''' may be determined by the [[Group]].
*[[Group 1]] [[Element]]s all form +1 [[ion]]s; Li<sup>+1</sup>, Na<sup>+1</sup>, K<sup>+1</sup>
*[[Group 2]] [[Element]]s all form +2 [[ion]]s; Be<sup>+2</sup>, Mg<sup>+2</sup>, Ca<sup>+2</sup>
*[[Group 3]] [[Element]]s all form +3 [[ion]]s; Al<sup>+3</sup>
[[Transition Metal]] [[Element]]s can form different [[ion]]s which are shown by [[Roman Numeral]]s; Iron can form [[Fe]](II) which is [[Fe]]<sup>+2</sup> or [[Fe]](III) is [[Fe]]<sup>+3</sup>,
Manganese can form [[Mn]](II) which is [[Mn]]<sup>+2</sup> or [[Mn]](IV) which is [[Mn]]<sup>+4</sup>.
: The more easily a [[metal]] [[element]] can become a '''metal ion''' the more [[reactivity|reactive]] the [[metal]].
