Qhov sib txawv tseem ceeb ntawm Yttrium thiab Ytterbium yog qhov ntuj yttrium tsis yog hluav taws xob, qhov ytterbium feem ntau yog xov tooj cua.
Yttrium thiab ytterbium yog cov ntsiab lus uas suab zoo sib xws, tab sis lawv txawv ntawm ib leeg raws li lawv cov tshuaj thiab lub cev.
Yttrium yog dab tsi?
Yttrium yog cov khoom siv tshuaj muaj lub cim Y thiab tus lej atomic 39. Nws zoo li cov hlau hloov pauv nyiaj-hlau. Chemically, nws zoo ib yam li lanthanide, thiab peb feem ntau faib nws raws li lub ntiaj teb tsis tshua muaj caij.
Daim duab 01: Qhov tshwm sim ntawm Yttrium Hlau
Ntxiv mus, peb tuaj yeem pom yttrium hlau nyob rau hauv lub xeev khov ntawm chav tsev kub. Nws tuaj yeem pom nyob rau hauv pawg 3 thiab lub sijhawm 5 ntawm lub sijhawm ntawm lub ntsiab lus. Nws yog d-block element. Qhov feem ntau oxidation xeev ntawm yttrium yog +3. Nws yog ib qho tsis muaj zog oxide compound. Lawm, nws tshwm sim yog primordial. Nws muaj hexagonal kaw-packed siv lead ua qauv. Yttrium muaj qhov xwm txheej paramagnetic.
Tsis tas li ntawd, thaum xav txog lub cev lub cev ntawm yttrium, nws yog ib qho mos, nws yog xim hlau, lustrous, thiab crystalline hlau. Nws yog comparatively tsawg electronegative. Yttrium yog ruaj khov nyob rau hauv huab cua bulk daim ntawv. Qhov no yog vim qhov passivation ntawm kev tiv thaiv oxide zaj duab xis uas tuaj yeem pom nyob rau saum npoo ntawm cov hlau.
Muaj ntau daim ntawv thov ntawm yttrium, suav nrog nws siv los ua cov khoom siv sintering hauv kev tsim cov ntxeem tau silicon nitride, ua cov khoom siv rau ethylene polymerization, hauv electrodes ntawm qee qhov ua haujlwm siab, hauv cov roj mantles rau propane lanterns, thiab kev tsim khoom ntawm hluavtaws garnets.
Ytterbium yog dab tsi?
Ytterbium yog cov khoom siv tshuaj muaj lub cim Yb thiab tus lej atomic 70. Nws zoo nkaus li cov hlau dawb-dawb nrog cov xim daj daj. Nws tuaj yeem pom raws li 14 th tshuaj lom neeg hauv lanthanide series, thiab nws tshwm sim nyob rau lub sijhawm 6 ntawm lub sijhawm ntawm cov tshuaj lom neeg. Nws yog f-block element. Peb tuaj yeem pom cov hlau no muaj nyob rau hauv cov khoom-lub xeev ntawm chav tsev kub.
Daim duab 02: Qhov tshwm sim ntawm Ytterbium Hlau
Ntxiv mus, qhov ruaj khov tshaj plaws oxidation xeev ntawm ytterbium yog +3. Nws qhov tshwm sim ntuj yog qhov tseem ceeb thiab muaj lub ntsej muag-centered cubic crystal qauv. Cov khoom sib nqus ntawm cov hlau no yog paramagnetic. Cov hlau tau pom los ntawm Jean Charles Galissard xyoo 1878.
Tsis tas li ntawd, peb tuaj yeem soj ntsuam ytterbium ua ib qho muag muag, malleable, thiab ductile chemical keeb uas tuaj yeem pom cov xim nyiaj thaum nws ntshiab. Peb tuaj yeem txheeb xyuas nws raws li lub ntiaj teb tsis tshua muaj. Cov hlau no yooj yim yaj hauv cov ntxhia ntxhia acids. Txawm li cas los xij, nws tuaj yeem maj mam hnov mob nrog dej txias thiab tuaj yeem ua rau oxidation maj mam hauv huab cua. Muaj peb lub isotopes loj ntawm cov hlau no: alpha, beta, thiab gamma isotopes.
Muaj ntau ntau yam kev siv ytterbium, uas suav nrog kev siv nws los ua ib qho chaw ntawm gamma rays, raws li kev ruaj ntseg atomic moos, rau doping ntawm stainless hlau, raws li ib tug dopant ntawm active media, nyob rau hauv kev tsim qubits rau quantum xam, etc.
Qhov txawv ntawm Yttrium thiab Ytterbium yog dab tsi?
Yttrium thiab ytterbium yog cov ntsiab lus uas suab zoo sib xws, tab sis lawv txawv ntawm ib leeg raws li lawv cov tshuaj thiab lub cev. Yttrium yog cov khoom siv tshuaj muaj lub cim Y thiab atomic tooj 39, thaum Ytterbium yog cov khoom siv tshuaj muaj lub cim Yb thiab atomic tooj 70. Qhov sib txawv tseem ceeb ntawm Yttrium thiab Ytterbium yog tias ntuj yttrium yog tsis muaj hluav taws xob, qhov ytterbium feem ntau yog xov tooj cua.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm Yttrium thiab Ytterbium hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Yttrium vs Ytterbium
Yttrium yog cov khoom siv tshuaj muaj lub cim Y thiab tus lej atomic 39, thaum Ytterbium yog cov khoom siv tshuaj muaj lub cim Yb thiab atomic naj npawb 70. Qhov sib txawv tseem ceeb ntawm Yttrium thiab Ytterbium yog qhov ntuj yttrium yog tsis muaj hluav taws xob, whereas ytterbium feem ntau yog cov xov tooj cua.
