====Neon====
[[Neon]] has three main stable isotopes:<sup>20</sup>Ne, <sup>21</sup>Ne and <sup>22</sup>Ne, with <sup>20</sup>Ne produced by cosmic [[nucleogenic]] reactions, causing high abundance in the atmosphere.<ref name="Ballentine-2002b"/><ref name="Wetherill 679–683">{{Cite journal |last=Wetherill |first=George W. |date=1954-11-01 |title=Variations in the Isotopic Abundances of Neon and Argon Extracted from Radioactive Minerals |url=https://journals.aps.org/pr/abstract/10.1103/PhysRev.96.679 |journal=Physical Review |volume=96 |issue=3 |pages=679–683 |doi=10.1103/PhysRev.96.679|bibcode=1954PhRv...96..679W }}</ref> <sup>21</sup>Ne and <sup>22</sup>Ne are produced in the earth's crust as a result of interactions between alpha and neutron particles with light elements; <sup>18</sup>O, <sup>19</sup>F and <sup>24,25</sup>Mg.<ref>{{Cite journal |last1=Yatsevich |first1=Igor |last2=Honda |first2=Masahiko |date=1997-05-10 |title=Production of nucleogenic neon in the Earth from natural radioactive decay |url=https://agupubs.onlinelibrary.wiley.com/doi/10.1029/97JB00395 |journal=Journal of Geophysical Research: Solid Earth |language=en |volume=102 |issue=B5 |pages=10291–10298 |doi=10.1029/97JB00395 |bibcode=1997JGR...10210291Y |issn=0148-0227}}</ref> The neon ratios (<sup>20</sup>Ne/<sup>22</sup>Ne and <sup>21</sup>Ne/<sup>22</sup>Ne) are systematically used to discern the heterogeneity in the [[Mantle (geology)|Earth's mantle]] and volatile sources.
