Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: 2H, imwe isotope yakagadzikana yehydrogen, inozivikanwa se deuterium uye ine proton imwe chete neineutron imwe chete mu nucleus. Deuterium yose iri muchadenga inofungidzirwa kuva yakabudiswa panguva yeBig Bang, uye yakatsungirira kubvira panguva iyoyo. Deuterium haina mwaranzi, uye haimiriri ngozi yakakomba yehupfu. Mvura ine mamorekuru ane deuterium panzvimbo pehydrogen yakajairika inonzi mvura inorema. Deuterium nemakemikari ayo anoshandiswa sechiratidzo chisina mwaranzi mukuedza kwemakemikari uye mumidziyo ye1H-NMR spectroscopy. Mvura inorema inoshandiswa sechinhu chinoderedza neutron uye chinotonhorera chemagetsi enyukireya. Deuterium ingagonawo kuva mafuta okushambadzira fusion yenyukireya.  Mubvunzo: Zita reimwe isotope yakatsiga yehydrogen rinonzi chii?
2H
