Qhov emission ntawm ib qho alpha particle los ntawm plutonium atom pib ib lub xov tooj cua decays, hu ua decay series. Cov kab lwj lwj rau Pu-239 tau pom hauv daim duab 1. Thaum pib, Pu-239 tso tawm ib qho alpha particle los ua U-235Thaum kawg, cov koob xaus nrog cov tsis muaj hluav taws xob isotope ntawm txhuas..
Thaum plutonium-239 dhau alpha decay dab tsi yog qhov tshwm sim ntawm atom?
Nws dhau los uranium-235.
Yuav ua li cas thaum plutonium-239 lwj?
Pu nws tus kheej lwj via alpha lwj mus rau 235U nrog ib nrab neej ntawm 24 100 xyoo.
Yuav ua li cas thaum plutonium dhau alpha lwj?
Plutonium-242 yuav dhau mus alpha lwj, uas txhais tau hais tias nws cov nucleus yuav tawm ib qho alpha particleIb qho alpha particle yog qhov tseem ceeb ntawm lub nucleus ntawm helium-4 atom, 42He. Raws li qhov tshwm sim ntawm alpha particle emission, lub nucleus 'atomic naj npawb yuav txo los ntawm 2 thiab nws cov huab hwm coj yuav txo los ntawm 4.
Dab tsi lwj yog plutonium-239?
Pu-239 lwj mus rau U-235, uas yog qhov pib ntawm Actinium Series. Pib nrog cov isotope U-235, qhov kev lwj no suav nrog cov khoom hauv qab no: Actinium, astatine, bismuth, francium, lead, polonium, protactinium, radium, radon, thallium, thiab thorium.
