	<onlyinclude>The '''nucleus''' is the central, highly dense, component of an [[atom]] ~~and~~ is composed of [[proton]]s and [[neutron]]s (collectively called [[nucleon]]s).</onlyinclude> It accounts for the vast majority of an atom's [[mass]], however, due to the nature of [[electron]]s and the [[electromagnetic force]] that keeps the electrons orbiting the nucleus, only a small amount of an atoms size ~~can be~~ attributed to the nucleus (the electron cloud accounts for the ~~majority~~).		<onlyinclude>The '''nucleus''' is the central and highly dense component of an [[atom]].

	==Holding the nucleus together==		==Holding the nucleus together==
	There are two [[fundamental force]]s ~~that were found~~ in the nucleus, that aren't observed outside of nuclei. These forces are creatively named the [[strong force]] and the [[weak force]]. Tellingly, the [[strong force]] is extremely strong, in fact it's the strongest force known in the universe, but only acts over extremely small distances within the nucleus. It holds the nucleus together despite the intense [[electromagnetic force]] pushing apart the protons.		There are two [[fundamental force]]s in the nucleus that aren't observed outside of nuclei. These forces are creatively named the [[strong force]] and the [[weak force]]. Tellingly, the [[strong force]] is extremely strong, in fact it's the strongest force known in the universe, but only acts over extremely small distances within the nucleus (about a [[meter\|fm]] or 10<sup>-15</sup> m). It holds the nucleus together despite the intense [[electromagnetic force]] pushing apart the protons.

	The [[weak force]] is about 1,000,000 times weaker than the [[electromagnetic force]], but still quite a bit stronger than [[gravity]]. It balances the number of protons and neutrons within the nucleus by allowing [[beta decay]] ~~(turning~~ protons into neutrons or neutrons into protons).		The [[weak force]] is about 1,000,000 times weaker than the [[electromagnetic force]], but still quite a bit stronger than [[gravity]]. It balances the number of protons and neutrons within the nucleus by allowing [[beta decay]], which converts protons into neutrons or neutrons into protons (depending on the type of beta decay).

	These two forces together allow the process of [[nuclear fusion]] to occur, which is essential to life - nuclear fusion ~~is what~~ powers the [[sun]]! They also allow the process of [[fission]] to occur which is ~~where~~ [[~~nuclear reactor~~]]~~s get their~~ [[~~power~~]]. Additionally, these forces govern what sorts of [[radioactive decay]] occur. These forces are both actively researched in physics.
