[[File:SodiumSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Sodium]].]]
[[Sodium]] is a [[Group 1]] [[element]] with an [[Atomic Number|atomic number]] of 11.
===About Sodium===
: [[Sodium]] has the [[Chemical Formula|chemical formula]] [[Sodium|Na]].
: [[Sodium]] has 11 [[proton]]s and 12 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 11 and an [[Relative Atomic Mass|atomic mass]] of 23.
: [[Sodium]] is a more [[Reactivity|reactive]] [[Alkali Metal|alkali metal]] than [[Lithium]] but less [[Reactivity|reactive]] than [[Potassium]].
: [[Sodium]] 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]].
: [[Sodium]] [[Chemical Reaction|reacts]] strongly with [[water]] to produce [[Hydrogen]] [[gas]] and [[Sodium Hydroxide]].
: [[Sodium]] is a [[solid]] at [[STP|room temperature]].
: An [[atom]] of [[Sodium]] has only 1 [[electron]] in its [[Outer Shell|outer shell]].
: [[Sodium]] [[ion]]s have lost an [[electron]] to become [[Positive Charged|positively charged]].
