Isotop Hidrogén

Saking Wikipédia
Isotop utama saking hidrogén (1H)
Iso­top Palu­ruhan
kalim­pahan paruh-idup (t1/2) mode pro­duk
1H [99.972%, 99.999%] tegteg
2H [0.001%, 0.028%] tegteg
3H jejak 12.32(2) y β− 3Hé
Bobot atom standar Ar°(H)[1.00784, 1.00811][1]

Hidrogén (1H) madué tiga isotop sané wénten sacara alami: 1H, 2H, miwah 3H. 1H saha 2H punika sané tegteg, asapunika 3H madué paruh urip 12.32 warsa.[2][nb 1] Isotop sane abot taler wenten; samian punika sintétis lan madué masa paruh urip kirang saking 1 zeptodetik.(10−21 s).[3][4]

Hidrogen wantah asiki datu sané isotopnyané madué wasta sané matiosan sané kantun kawigunayang ngantos mangkin: 2H is deutérium[5] and 3H is tritium.[6] Simbol D lan T kadang-kadang kaanggen ring deuterium lan tritium; IUPAC (Uni Internasional Kimia Murni lan Terapan) nerima pralambang inucap, nanging ngusulang pralambang isotop standar 2H miwah 3H, mangda nénten bingung ring penyortiran abjad rumus kimia.[7] 1H, tanpa néutron, prasida kasengguh protium antuk ngicalang ambiguitas.[8] Salami pangawit paplajahan indik radioaktivitas, makudang-kudang radioisotop baat tiosan kaicen wastan, nanging wasta sekadi punika arang kawigunayang mangkin.

Tiga isotop hidrogén sané pinih tegteg: protium (A = 1), deutérium (A = 2), miwah tritium (A = 3)
