Thulium yog tshuaj lom neeg keeb nrog lub cim Tm thiab atomic tooj 69. Nws yog lub kaum peb thiab thib peb-kawg keeb nyob rau hauv lub lanthanide series.
Ua raws li qhov no hauv kev xav, dab tsi yog thulium?
Siv thiab cov khoom Ib lub ci, silvery hlau. Siv. Thaum irradiated nyob rau hauv ib tug nuclear reactor, thulium tsim ib qho isotope uas emits x-rays. Ib lub 'khawm' ntawm cov isotope no yog siv los ua lub teeb yuag, nqa lub tshuab x-ray siv rau kev kho mob. Thulium yog siv nyob rau hauv lasers nrog rau kev phais.
Kuj Paub, qhov twg yog thulium pom? Lub ntsiab tsis yog pom nyob rau hauv qhov nyob rau hauv daim ntawv ntshiab tab sis nws yog pom nyob rau hauv me me nyob rau hauv minerals nrog rau lwm yam tsawg earths. Nws yog feem ntau muab rho tawm los ntawm monazite, uas muaj txog 0.007% ntawm thulium thiab bastnasite (li 0.0008%). Lub ntsiab ore yog nyob rau hauv Tuam Tshoj, Teb Chaws Asmeskas, Brazil, Is Nrias teb, Sri Lanka thiab Australia.
Ntawm no, yog thulium yog hlau?
Thulium yog ib qho ci, mos, malleable, silvery-grey hlau . Nws yog lub ntiaj teb tsis tshua muaj hlau thiab yog ib qho ntawm qhov tsawg tshaj plaws.
Puas yog thulium muaj zog?
Cov ntsiab lus no yog a khov kho . Thulium cais raws li ib feem ntawm Lanthanide series raws li ib qho ntawm "Rare Earth Elements" uas tuaj yeem nyob hauv Pawg 3 cov ntsiab lus ntawm Lub Sijhawm Table thiab hauv 6th thiab 7th lub sijhawm.

Yog vim li cas magnesium nyob rau lub sij hawm 3 ntawm lub sij hawm?
Cov qauv ntawm cov khoom hloov pauv thaum koj mus hla lub sijhawm. Thawj peb yog hlau, silicon yog loj covalent, thiab tus so yog cov molecules yooj yim. Sodium, magnesium thiab aluminium tag nrho muaj cov qauv hlau. Nyob rau hauv magnesium, ob qho tib si ntawm nws sab nrauv electrons koom nrog, thiab nyob rau hauv txhuas tag nrho peb
Lub square ntawm lub sij hawm lub sij hawm hu ua dab tsi?
Lub ib hlis ntuj 24, 2016. Txhua square ntawm lub periodic rooj muab yam tsawg kawg nkaus lub npe ntawm lub caij, nws cov cim, atomic tooj thiab txheeb ze atomic mass (atomic hnyav)
Lub sij hawm twg yog californium nyob rau hauv lub sij hawm?
Cov khoom no yog ib qho khoom. Californium tau muab cais ua ib feem ntawm Actinide series raws li ib qho ntawm 'Rare Earth Elements' uas tuaj yeem nyob hauv Pawg 3 cov ntsiab lus ntawm Lub Sij Hawm Lub Sijhawm thiab hauv 6th thiab 7th lub sijhawm. Lub Ntiaj Teb Rare Elements yog ntawm Lanthanide thiab Actinide series
Lub sij hawm ntawm lub sij hawm geology yog dab tsi?
Cov sij hawm no tsim cov ntsiab lus ntawm kev sib faib ntawm cov geologists tau faib lub ntiaj teb keeb kwm. Eons thiab eras yog cov subdivisions loj dua lub sij hawm thaum lub sij hawm lawv tus kheej yuav muab faib ua epochs thiab hnub nyoog. Cov pob zeb tsim nyob rau hauv ib lub sij hawm yog nyob rau hauv lub stratigraphic unit hu ua ib tug system
Cov kab ntsug nyob rau hauv lub sij hawm lub sij hawm sawv cev li cas?
Cov kab ntsug ntawm lub sij hawm teev npe hu ua pab pawg lossis tsev neeg vim lawv cov tshuaj lom neeg zoo sib xws. Txhua tus tswv cuab ntawm tsev neeg ntawm cov ntsiab lus muaj tib tus lej ntawm valence electrons thiab cov khoom siv tshuaj zoo sib xws. Cov kab kab rov tav ntawm lub rooj ntu ntu yog hu ua lub sijhawm
