		+	===Meaning===
		+	A [[Chemical Reaction]] is when the [[atom]]s in [[molecule]]s break their [[Chemical Bond\|bonds]] and form new [[Chemical Bond\|bonds]], usually with other [[atom]]s.
		+
		+	===About Chemical Reactions===
		+	: In a '''chemical reaction''' the [[atom]]s rearrange to form a new [[substance]].
		+	: '''Chemical reactions''' often need some [[energy]] to start, like [[combustion]] where the [[fuel]] needs to be [[Heat\|heated]] to start.
		+	: If a '''chemical reaction''' gives off more energy than it needs to start then it is called an [[exothermic]] '''reaction'''. In these '''reactions''' the [[temperature]] increases.
		+	: If a '''chemical reaction''' takes in more energy than it gives out then it is called an [[endothermic]] '''reaction'''. In these '''reactions''' the [[temperature]] decreases.
		+	There are three ways that '''chemical reactions''' can happen:
		+	*[[Electron Transfer]] - [[Electron]]s from the [[Outer Shell]] of one [[atom]] move to the [[Outer Shell]] of another [[atom]] to form an [[Ionic Bond]].
		+	*[[Proton Transfer]] - [[Hydrogen#Ion\|Hydrogen Ions]] are removed from an [[acid]] and added to a [[base]].
		+	*[[Electron Sharing]] - [[Electron]]s in the [[Outer Shell]] of one [[atom]] are shared with the [[Outer Shell]] of another [[atom]].
		+	*[[Electron Sharing]]
