Qhov sib txawv tseem ceeb ntawm rubidium thiab niobium yog rubidium yog alkali hlau, qhov niobium yog hlau hloov pauv.
Rubidium thiab niobium yog ob yam tshuaj sib txawv. Rubidium yog ib qho s thaiv cov khoom nyob rau hauv lub sij hawm lub sij hawm, thiab nws yog nyob rau hauv pawg 1, uas peb feem ntau hu ua alkali hlau pawg. Niobium yog ib qho d block chemical, thiab nws muaj ib qho hluav taws xob tsis sib xws, uas ua rau lub npe hloov pauv hlau.
Rubidium yog dab tsi?
Rubidium yog cov khoom siv tshuaj lom neeg muaj cov cim tshuaj Rb thiab tus lej atomic 37. Nws yog cov hlau mos heev uas muaj cov xim dawb-dawb. Cov hlau no yog nyob rau hauv alkali hlau pawg ntawm lub sij hawm lub rooj. Nws muaj qhov sib xws nrog cov poov tshuaj, uas yog cov tshuaj lom neeg hauv tib pawg. Cov tsos ntawm rubidium zoo ib yam li cov hlau hlau. Cov khoom xws li lub cev zoo li, softness, thiab conductivity zoo ib yam li cov hlau Cesium. Feem ntau, peb tsis tuaj yeem khaws rubidium hlau nyob rau hauv qhov muaj cov pa hauv huab cua vim tias nws tuaj yeem ua rau muaj kev kub ntxhov heev uas tuaj yeem ua rau hluav taws kub.
Ntawm cov tshuaj lom neeg hauv pawg hlau alkali, rubidium yog thawj cov hlau uas muaj qhov ntom ntom uas siab dua qhov ntom ntawm cov dej. Yog li ntawd, thaum ntxiv rau dej, rubidium hlau nyhav rau hauv dej. Muaj ob lub isotopes loj ntawm rubidium uas tshwm sim ib txwm: 85-Rb thiab 87-Rb. Ntawm lawv, 85-Rb yog cov isotope tshaj plaws. 87-Rb tuaj yeem lees paub tias yog cov hlau me me.
Daim duab 01: Rubidium Hlau
Cov hlau no tau tshawb pom los ntawm ob tus kws tshawb fawb Robert Bunsen thiab Gustav Kirchhoff, xyoo 1861. Txoj kev uas lawv siv rau qhov kev tshawb pom no yog nplaim taws spectroscopy. Lawv hu ua cov hlau xws li raws li lo lus Latin rubidius, lub ntsiab lus "liab liab", uas yog xim ntawm rubidium nyob rau hauv nws emission spectrum.
Muaj ntau ntau yam kev siv rubidium. Nws yog siv nyob rau hauv cov foob pob hluav taws uas ua rau lawv cov xim liab. Nws kuj tseem siv rau hauv lub tshuab hluav taws xob, siv los ua ib hom atomic tshaj plaws hauv cov txheej txheem laser txias, siv rau polarizing Helium uas tsim cov hlau nplaum Helium roj, ua cov kua dej ua haujlwm hauv vapor turbines, thiab lwm yam.
Niobium yog dab tsi?
Niobium yog cov khoom siv tshuaj uas muaj cov cim tshuaj Nb thiab tus lej atomic 41. Cov tshuaj no tseem hu ua columbium. Nws yog cov hlau hloov pauv uas muaj lub teeb grey zoo li thiab cov qauv crystalline. Feem ntau, cov ntaub ntawv ntshiab ntawm niobium muaj qhov nyuaj uas zoo ib yam li cov hlau titanium. Lub ductility zoo ib yam li cov hlau. Feem ntau, peb tuaj yeem pom tias cov hlau no oxidizes nyob rau hauv lub xub ntiag ntawm lub ntiaj teb huab cua qeeb heev. Qhov no ua rau nws tseem ceeb hauv cov ntawv thov ntsig txog kev lag luam jewelery.
Daim duab 02: Niobium
Niobium tau tshawb pom los ntawm Askiv kws chemist Charles Hatchett hauv xyoo 1801, uas tau muab nws lub npe hu ua columbium. Tom qab ntawd, German chemist Heinrich Rose renamed no hlau niobium. Lub npe columbium tau muab los ntawm nws lub npe ore, columbite. Lub npe niobium los ntawm Greek mythology, thiab lub npe no los ntawm "Niobe", uas yog tus ntxhais ntawm "Tantalus".
Muaj ntau yam kev siv ntawm niobium, xws li qib high-qib qauv steel ntau lawm, superalloy ntau lawm, lwm yam niobium-raws li alloy productions, siv los ua superconducting hlau nplaum, siv los ua superconductors, thiab lwm yam.
Qhov txawv ntawm Rubidium thiab Niobium yog dab tsi?
Rubidium yog s block chemical keeb thiab niobium yog d block chemical element. Txawm li cas los xij, peb tuaj yeem txheeb xyuas lawv ob qho tib si li hlau. Qhov sib txawv tseem ceeb ntawm rubidium thiab niobium yog rubidium yog alkali hlau, thaum niobium yog hlau hloov. Peb tuaj yeem yooj yim paub qhov txawv ntawm cov qauv ntawm rubidium thiab niobium los ntawm kev ntxiv cov qauv rau dej; rubidium muab cov tshuaj tiv thaiv exothermic thaum niobium qhia tsis muaj qhov cuam tshuam loj heev.
Cov duab hauv qab no qhia ntau qhov sib txawv ntawm rubidium thiab niobium hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Rubidium vs Niobium
Rubidium thiab niobium yog cov tshuaj lom neeg uas peb tuaj yeem hu ua hlau. Tab sis lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv, yog li, kev siv sib txawv thiab. Qhov sib txawv tseem ceeb ntawm rubidium thiab niobium yog rubidium yog alkali hlau, thaum niobium yog hlau hloov.
