Mercury yog tib lub hlau uas, ntawm chav tsev kub, tseem yog kua. Txawm li cas los nws tseem yog ib nkaws hlau, txawm nyob rau hauv nws lub xeev ruaj khov. Qhov no yog vim Mercury tsis nyiam kev sib raug zoo nrog nws tus kheej, thiab yog heev resistant rau bonding nrog rau lwm yam. Mercury yuav tsim cov roj ntawm 357 degrees centigrade.
Tsis tas li ntawd, yog Mercury malleable?
Mercury yog silvery-dawb tshuaj lom metallicelement. Nws chemical symbol ( Hg ) los ntawm hydrargyrum los ntawm Greek lo lus hydrargyros lub ntsiab lus 'dej' thiab 'nyiaj'. Mercury yog cais raws li "Transition Hlau" raws li nws yog ductile , tuaj yeem , thiab muaj peev xwm ua tau cua sov thiab hluav taws xob.
Tsis tas li ntawd, yuav ua li cas thaum mercury evaporates? Thaum poob, elemental mercury rhuav tshem cov tee me me uas tuaj yeem dhau los ntawm cov kab nrib pleb me me lossis ua rau muaj zog txuas rau qee yam khoom. Nyob rau hauv chav tsev kub, nthuav tawm elemental mercury ua tau evaporate los ua aninvisible, odorless toxic vapor. Yog tias cua sov, nws yog xim tsis muaj xim, tsis muaj ntxhiab tsw.
Hauv qhov no, puas yog mercury yog hlau lossis tsis yog hlau?
Ib qho hnyav, silvery d-block element, mercury yog theonly nws yog xim hlau cov khoom uas yog kua ntawm tus qauv tej yam kev mob rau kub thiab siab; Tsuas yog lwm cov khoom uas ua kua hauv cov xwm txheej no yog halogen bromine, txawm li cas los xij hlau xws li caesium, gallium, thiab rubidium yaj tsuas yog saum chav sov.
mercury xav li cas?
[edit] Mercury yog ib tug silvery hlau uas yog liquidat chav tsev kub. Nws yog tuab heev, uas txhais tau hais tias nws hnyav heev txawm tias koj tsis muaj ntau heev.

Lub wavelength ntawm mercury yog dab tsi?
Tsuas yog lub teeb ntawm 253 nm tuaj yeem siv tau. Fused silica yog siv nyob rau hauv kev tsim khoom kom 184 nm lub teeb los ntawm absorbed. Nyob rau hauv nruab nrab-siab mercury-vapor teeb, cov kab ntawm 200-600 nm yog tam sim no. Emission kab spectrum. Wavelength (nm) Lub Npe (saib photoresist) Xim 435.8 G-kab xiav 546.1 ntsuab 578.2 daj-txiv kab ntxwv
Mercury puas yog luster?
Yog lawm, mercury hlau nyob rau hauv cov ntaub ntawv ua kua muajluster (los yog lustre, ob qho tib si zoo li raug sau ntawv). Nws yog cov yam ntxwv ntawm cov hlau, thiab cov khoom siv hluav taws xob (electrons txav dawb txawm tias cov khoom siv) uas ua rau "metalic" ci, thiab yog li theluster
Puas yog mercury oxide soluble?
Lus Txhais rau liab mercuric oxide (2 ntawm 2) ib tug me ntsis crystalline, dej-soluble, tshuaj lom compound, HgO, tshwm sim raws li ib tug ntxhib, txiv kab ntxwv-liab hmoov (liab mercuric oxide) los yog nplua, txiv kab ntxwv-daj hmoov (daj mercuric oxide. ): siv tseem ceeb raws li ib tug pigment nyob rau hauv cov xim thiab raws li ib tug antiseptic nyob rau hauv pharmaceuticals
Puas muaj cua ntawm Mercury?
Txij li Mercury tsis tshua muaj huab cua, nws tsis muaj huab cua zoo li cua daj cua dub, huab cua, cua lossis nag. Nws qhov kub thiab txias tuaj yeem ncav cuag 801 Fahrenheit thaum nruab hnub (vim tias nws nyob ze rau lub hnub) thiab tuaj yeem poob mus rau -279 Fahrenheit thaum hmo ntuj (vim tias tsis muaj cua sov rau nruab hnub)
Puas yog Mercury yog cov tshuaj dawb huv lossis sib xyaw?
Mercury ntshiab tsis muaj dab tsi ntxiv tab sis mercury; Nws yog ib qho khoom siv, ib qho ntawm cov khoom siv tshuaj lom neeg los ntawm cov tshuaj lom neeg thiab cov khoom sib xyaw ua ke. Tag nrho cov mercury atoms nyob rau hauv nws yog tib yam, nrog atomic tooj 80. Nws kuj tshwm sim los ua ib tug hlau, zoo li kub los yog nyiaj, uas nws purity yuav ntsuas tau
