Siv ntawm Seaborium
Feem ntau cov khoom siv hluav taws xob yog siv nyob rau hauv lub laboratory rau kev sim. Tej zaum lawv yog siv rau ua lwm yam los yog ua siv nyob rau hauv nuclear reactors.
Ntawm no, qhov twg tuaj yeem pom seaborgium?
Discovery ntawm Seaborgium Seaborgium tau tsim thawj zaug hauv xyoo 1974 ntawm Lawrence-Berkeley Laboratory , Tebchaws Asmeskas, los ntawm pab pawg kws tshawb fawb coj los ntawm Albert Ghiorso thiab ntawm Lub Tsev Haujlwm Sib Koom rau Nuclear Research ntawm Dubna, Russia. Lub ntsiab lus tau muab npe tom qab Nobel nqi zog tus yeej Glenn Theodore Seaborg, American nuclear chemist.
Tsis tas li ntawd, seaborium zoo li cas? Seaborium yog ib qho khoom siv hluav taws xob tsim hluav taws xob, nws qhov zoo li tsis paub, nws tej zaum muaj xim dawb lossis xim hlau xim grey. Qhov ruaj khov tshaj plaws isotope Sg 271 muaj ib nrab lub neej ntawm 2.4 feeb. Seaborium tsis pom dawb nyob rau hauv ib puag ncig, vim nws yog ib qho khoom siv hluavtaws.
Ib yam li ib tug yuav nug, peb siv seaborgium li cas?
Seaborium cov feem ntau ruaj khov isotope, seaborium -271, muaj ib nrab-lub neej ntawm li 2.4 feeb. Nws lwj mus rau hauv rutherfordium-267 los ntawm alpha decays los yog decays los ntawm spontaneous fission.. Txij li thaum tsuas yog ob peb atoms ntawm seaborium puas tau ua, muaj yog tam sim no tsis muaj siv rau seaborium sab nraum qhov kev tshawb fawb txog kev tshawb fawb.
Dab tsi yog seaborium npe tom qab?
Lo lus Keeb Kwm: Seaborium yog npe rau Influential American chemist Glenn Seaborg, uas yog nyob rau hauv pab pawg uas nrhiav pom americium, plutonium, nobelium, mendelevium, berkelium, californium, curium thiab thorium. Nws tau txais Nobel nqi zog hauv Chemistry hauv xyoo 1951.
Pom zoo:
Puas yog seaborium yog hlau?
Tau qhov twg los: Seaborium yog cov khoom siv hluav taws xob, hluav taws xob hlau, tsim los ntawm kev foob pob hluav taws xob. Nws tsuas yog ua tau me me xwb. Cov hlau yog tsim los ntawm bombarding californium-249 nrog hnyav oxygen ions. Isotopes: Seaborgium muaj 11 isotopes uas nws ib nrab-lub neej paub, nrog cov lej loj ntawm 258 txog 271
Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
