	<onlyinclude>An ion is ~~an [[atom]]~~ with a net positive or negative [[charge]].</onlyinclude> Ions ~~occur~~ when ~~the number of electrons around a~~ [[~~nucleus~~]] ~~doesn't exactly equal~~ the number of [[proton]]s in the ~~nucleus. The number of~~ [[~~neutron~~]]~~s in the nucleus has~~ no ~~effect on whether or not a given atom is an ion since they~~ have ~~no charge~~, ~~although changing the number of neutrons does change the [[isotope]]~~.		<onlyinclude>An ion is a particle with a net positive or negative [[charge]].</onlyinclude> Ions may be formed from single [[atom]]s ("monatomic ions") or from [[molecule]]s ("molecular ions" or "complex ions"). An atom or molecule can become charged when it either gains or loses an [[electron]] so that the number of electrons and [[proton]]s in the [[nucleus]] are no longer equal. Ions that have at least one 'extra' electron are negatively charged, and are called <em>anions</em>. Ions that have lost at least one electron are positively charged, and are called <em>cations</em>.

	Ions are very chemically reactive (~~that means that~~ they easily undergo [[chemical reaction]]s), which can cause problems in biological systems. There are a number of ~~chemical~~ ways to produce ions~~, like dissolving salt in~~ [[~~water~~]], ~~or the process of~~ [[~~combustion~~]]. Additionally, [[radiation]] can ~~produce ions if~~ the radiation ~~has enough energy; this~~ is ~~referred to as~~ [[ionizing radiation]].		Ions are very chemically reactive (they easily undergo [[chemical reaction]]s), which can cause problems in biological systems. There are a number of ways to produce ions: some chemical reactions ([[combustion]] for example) will produce ionic products, and ionic compounds (like salt) will [[dissociate]] in water to release ions into solution. Additionally, if [[radiation]] with enough energy hits an atom or molecule, it can eject an electron from the atom or molecule, creating a cation. High-energy radiation capable of creating ions from neutral atoms or molecules is collectively called [[ionizing radiation]].
