Qhov sib txawv tseem ceeb ntawm curium 242 thiab curium 244 yog curium 242 muaj 146 neutrons hauv nws cov atomic nucleus whereas curium 244 muaj 148 neutrons hauv nws cov atomic nucleus.
Curium yog cov khoom siv tshuaj muaj tus lej atomic 96 thiab cov cim tshuaj Cm. Nws muaj ib tug xov tooj ntawm isotopes, uas muaj tib lub atomic tooj tab sis txawv pawg. Curium 242 thiab curium 244 yog ob lub isotopes ntawm cov tshuaj lom neeg curium.
Curium 242 yog dab tsi?
Curium 242 yog ib qho isotope ntawm cov khoom siv tshuaj curium. Nws muaj atomic tooj 96 thiab huab hwm coj 242. Qhov ntawd txhais tau tias, muaj 96 protons nyob rau hauv lub atomic nucleus ntawm curium atom nrog rau 146 neutrons. Lub atomic loj ntawm curium 242 yog kwv yees li 242.0588 amu. Cov cim tshuaj rau cov isotope no yog 242Cm. Nws yog cov tshuaj lom neeg muaj zog heev uas muaj ib nrab-lub neej nyob ib ncig ntawm 162 hnub. Txawm li cas los xij, cov isotope no yog ib qho hluav taws xob hluav taws xob uas tsis tuaj yeem pom hauv qhov xwm txheej. Feem ntau, kev lwj ntawm cov tshuaj no tshwm sim ntawm alpha lwj. Nws tsim Plutonium-238 thaum alpha lwj.
Daim duab 01: Curium
Cov curium 242 yog thawj cov isotope ntawm tag nrho cov isotopes ntawm curium los tsim hauv chav kuaj (hauv xyoo 1944). Nws yog tsim los ntawm bombarding plutonium-238 nrog alpha hais, uas yog tus txheej txheem ntawm alpha lwj ntawm no isotope. Tom qab ntawd, 240-curium isotope tau tsim nyob rau hauv tib txoj kev siv helium-4 es tsis txhob alpha hais. Sib nrug los ntawm alpha decay ntawm curium 242, peb tuaj yeem soj ntsuam nws qhov sib txawv ntawm tus kheej ib yam nkaus.
Curium 244 yog dab tsi?
Curium 244 yog ib qho isotope ntawm curium tshuaj lom neeg uas muaj atomic tooj 96 thiab huab hwm coj 244. Qhov ntawd txhais tau tias, muaj 96 protons nrog rau 148 neutrons hauv atomic nucleus ntawm curium 244 atom. Peb tuaj yeem pom cov curium 244 isotope li 244cm. Lub atomic mass ntawm no isotope yog 244.0627 amu. Tsis tas li ntawd, qhov no isotope tshwm sim raws li cov khoom siv hluav taws xob. Yog li ntawd, peb tuaj yeem hu nws ua radioisotope. Lub neej ib nrab ntawm cov isotope no yog kwv yees li ntawm 18 xyoo, uas yog tus nqi siab heev piv rau 242 curium radioisotope. Feem ntau, nws nyhav dhau los ntawm cov hluav taws xob tawg los ua plutonium-240. Ntawm no, peb tuaj yeem soj ntsuam qhov alpha lwj ntawm curium 244. Tsis tas li ntawd, qhov no kuj yog cov khoom siv hluav taws xob hluav taws xob thiab nws tuaj yeem ua rau lub cev tsis muaj zog ib yam nkaus.
Qhov txawv ntawm Curium 242 thiab Curium 244 yog dab tsi?
Curium yog cov khoom siv tshuaj muaj tus lej atomic 96 thiab cov cim tshuaj Cm. Curium 242 thiab curium 244 yog ob ntawm ntau lub xov tooj cua isotopes ntawm curium tshuaj keeb. Qhov sib txawv tseem ceeb ntawm curium 242 thiab curium 244 yog curium 242 muaj 146 neutrons nyob rau hauv nws atomic nucleus whereas curium 244 muaj 148 neutrons hauv nws atomic nucleus.
Ntxiv mus, ib nrab lub neej ntawm curium 242 qis dua piv rau curium 244. Qhov tseeb, ib nrab lub neej ntawm curium 242 yog li 16 hnub thaum lub neej ib nrab ntawm curium 244 yog li 18 xyoo.
Hauv qab infographic qhia txog qhov sib txawv ntawm curium 242 thiab curium 244.
Summary – Curium 242 vs Curium 244
Curium yog cov khoom siv tshuaj muaj atomic tooj 96 thiab cov cim tshuaj Cm. curium 242 thiab curium 244 yog ob ntawm ntau lub xov tooj cua isotopes ntawm curium tshuaj keeb. Qhov sib txawv tseem ceeb ntawm curium 242 thiab curium 244 yog curium 242 muaj 146 neutrons nyob rau hauv nws atomic nucleus whereas curium 244 muaj 148 neutrons hauv nws atomic nucleus.
