Carbon has two &lt;a href=&quot;/Category:StableIsotope&quot; title=&quot;Category:StableIsotope&quot;&gt; stable isotopes&lt;/a&gt;: the light isotope &lt;sup&gt;12&lt;/sup&gt;C (abundance: 98.9%, mass: 12.000000 amu) and the heavy isotope &lt;sup&gt;13&lt;/sup&gt;C (abundance: 1.1%, mass: 13.003355 amu). Since the mass of &lt;sup&gt;13&lt;/sup&gt;C is higher than the mass of &lt;sup&gt;12&lt;/sup&gt;C, the carbon isotopes are fractionated by chemical and biological processes. In general, &lt;sup&gt;12&lt;/sup&gt;C is strongly partitioned into organic matter (reduced form) while the heavy isotope is concentrated in the oxidized forms of carbon.<br /> &lt;/p&gt;<br /> <br /> &lt;!-- Do not edit below this unless you know what you are doing --&gt;<br /> <br /> Category Semantics<br /> * Sub-Class of<br /> ** [[subcategory of::Category:StableIsotope]]<br /> <br /> [[Category:StableIsotope]]</div>
