===Meaning===
[[Magnesium]] is a [[Group 2]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 12.
===About Magnesium===
====Molecular Structure====: [[Magnesium]] has the [[Chemical FormulaSymbol|chemical formulasymbol]] [[Magnesium|Mg]].: [[Magnesium]] [[atom]]s join together in large numbers to form a giant [[metal]] [[molecule]].====Atomic Structure====
: [[Magnesium]] as 12 [[proton]]s and 12 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 12 and an [[Relative Atomic Mass|atomic mass]] of 24.
: An [[atom]] of [[Magnesium]] has only 2 [[electron]]s in its [[Outer Shell|outer shell]].
====Properties====
: [[Magnesium]] is a more [[Reactivity|reactive]] [[Alkali Earth Metal|alkali earth metal]] than [[Beryllium]] but less [[Reactivity|reactive]] than [[Calcium]].
: [[Magnesium]] is more [[Reactivity|reactive]] than [[Carbon]] on the [[Reactivity Series|reactivity series]] so it must be [[Extraction of Metals|extracted]] from its [[ore]] using [[electrolysis]].
: [[Magnesium]] [[Chemical Reaction|reacts]] slowly with [[liquid]] [[water]] and strongly with [[steam]] to produce [[Hydrogen]] [[gas]] and [[Magnesium Hydroxide]] and strongly with [[acid]] to produce a [[Magnesium]] [[salt]]s.
: [[Magnesium]] burns at a very high [[temperature]] with a bright white flame.
: [[Magnesium]] is a [[solid]] at [[STP|room temperature]].

===About Magnesium===
====Molecular Structure====
: [[Magnesium]] has the [[Chemical Formula|chemical formula]] [[Magnesium|Mg]].
: [[Magnesium]] [[atom]]s join together in a [[Giant Metallic Structure|giant metallic structure]].
====Atomic Structure====
: The most [[Stable Isotope|stable isotope]] of [[Magnesium]] has 12 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Relative Atomic Mass|atomic mass]] of 24.
: An [[atom]] of [[Magnesium]] has only 2 [[electron]]s in its [[Outer Shell|outer shell]].
: [[Magnesium]] [[ion]]s have lost two [[electron]]s to become [[Positive Charge|positively charged]].
