Cov Actinides . Cov Actinide series muaj cov ntsiab lus nrog cov lej atomic 89 txog 103 thiab yog pawg thib rau hauv daim ntawv qhia hnub . Cov koob yog kab hauv qab ntawm Lanthanide series, uas yog nyob rau hauv qab lub ntsiab lub cev ntawm lub daim ntawv qhia hnub . Lanthanide thiab Actinide Series yog ob qho tib si hu ua Rare Earth Metals.
Tib neeg kuj nug, lanthanides thiab actinides nyob qhov twg ntawm lub rooj zaum?
Yog vim li cas Lanthanides thiab Actinides nyob rau hauv qab ntawm lub periodical rooj yog vim hais tias ntawm lawv cov khoom thiab nyob rau hauv lub block nyob rau hauv uas electrons sau. Cov cov lanthanides suav nrog cov ntsiab lus 58 txog 71 (ua tiav 4f subshell) thiab cov actinides suav nrog cov ntsiab lus 89 txog 103 (ua rau 5f subshell).
muaj pes tsawg actinides nyob rau hauv lub sij hawm? Cov actinide series suav nrog 15 lub ntsiab lus nrog tus lej atomic los ntawm 89 rau 103 . Feem ntau ntawm cov ntsiab lus no tsis tshwm sim ib txwm muaj tab sis tau tsim los ntawm cov kws tshawb fawb.
Tom qab ntawd, pom cov actinides nyob qhov twg?
Thorium thiab uranium yog tib yam pom actinides nyob rau hauv lub ntiaj teb crust nyob rau hauv qhov muaj nuj nqis, txawm hais tias me me ntawm neptunium thiab plutonium tau ua. pom hauv uranium ore. Actinium thiab protactinium yog pom Nyob rau hauv cov xwm li lwj cov khoom ntawm ib co thorium thiab uranium isotopes.
Qhov twg ob actinides tshwm sim nyob rau hauv lub ntiaj teb?
Lub xwb ob actinides pom nyob rau hauv cov khoom muaj nqis nyob rau hauv Lub ntiaj teb Cov tawv nqaij yog thorium thiab uranium. Qhov me me ntawm plutonium thiab neptunium muaj nyob rau hauv uranium xaj. Actinium thiab protactinium tshwm sim Raws li cov khoom lwj ntawm qee cov thorium thiab uranium isotopes.

Qhov loj ntawm lub rooj zaum nyob qhov twg?
Nyob rau lub sij hawm lub sij hawm, tus lej loj feem ntau yog nyob hauv qab lub cim cim. Tus lej loj uas tau teev tseg yog qhov nruab nrab loj ntawm tag nrho cov ntsiab lus isotopes. Txhua lub isotope muaj qee feem pua ntawm qhov muaj nyob hauv cov xwm txheej, thiab cov no tau ntxiv thiab nruab nrab kom tau txais cov lej nruab nrab
Rubidium nyob qhov twg ntawm lub rooj zaum?
Nws yog qhov tsis tshua muaj, txawm hais tias nws yog 16th feem ntau cov khoom nyob rau hauv lub ntiaj teb crust. Rubidium yog tam sim no nyob rau hauv ib co minerals pom nyob rau hauv North America, South Africa, Russia, thiab Canada. Nws muaj nyob rau hauv qee cov poov tshuaj minerals (lepidolites, biotites, feldspar, carnallite), qee zaum nrog cesium thiab
Qhov loj me ntawm atomic ntawm lub rooj zaum nyob qhov twg?
Muaj peb yam tseem ceeb uas pab hauv kev kwv yees ntawm cov xwm txheej hauv Lub Sijhawm Teem Sijhawm: tus naj npawb ntawm cov protons hauv lub nucleus, tus lej ntawm lub plhaub, thiab cov nyhuv thaiv. Lub atomic loj nce los ntawm sab saum toj mus rau hauv qab nyob rau hauv txhua pab pawg neeg raws li ib tug tshwm sim ntawm nce nyob rau hauv tag nrho cov ntawm peb yam
