: [[Sodium]] [[atom]]s join together in a [[Giant Metallic Structure|giant metallic structure]].
====Atomic Structure====
: The most [[Stable Isotope|stable isotope]] of [[Sodium]] has 12 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Relative Atomic Mass|atomic mass]] of 23.
: 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]].
====Properties====
: [[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]].
