Qhov sib txawv tseem ceeb ntawm npib tsib xee thiab nyiaj yog tias lub ntsiab lus melting ntawm npib tsib xee yog nyob ib puag ncig ob zaug siab dua qhov kub ntawm cov nyiaj. Txawm hais tias muaj tshuaj sib txawv, ob qho tib si cov hlau no yog ci ntsa iab thiab zoo sib xws. Txawm li cas los xij, tsis zoo li nyiaj, npib tsib xee muaj me ntsis golden tinge.
Nickel thiab nyiaj yog ob yam tshuaj uas poob rau hauv qeb ntawm cov hlau. Ntxiv mus, ob qho tib si cov ntsiab lus tshuaj yog nyob rau hauv d block ntawm lub sij hawm lub sij hawm ntawm lub ntsiab lus.
Nickel yog dab tsi?
Nws yog cov khoom siv tshuaj muaj tus lej atomic 28 thiab cov cim tshuaj Ni. Nws zoo li nyiaj vim tias ob qho tib si muaj lub ntsej muag zoo nkauj. Txawm li cas los xij, tsis zoo li nyiaj, qhov no muaj me ntsis golden tinge. Qee cov ntsiab lus tseem ceeb ntawm nickel muaj raws li hauv qab no.
- Atomic naj npawb=28
- Atomic mass=58.69 amu
- Electron configuration=[Ar] 3d84s2
- Lub cev lub cev=khoom ntawm chav sov
- Position in the periodic table=group 10, period 4 (d block)
- Melting point=1455°C
- Boiling point=2913°C
- Isotopes=Ni-58, Ni-60 thiab Ni-62 yog cov isotopes tseem ceeb
Daim duab 1: Ib Qho ntawm Nickel
Feem ntau, npib tsib xee tiv thaiv corrosion txawm nyob rau qhov kub thiab txias. Tsis tas li ntawd, nws yog cov hlau nplaum heev uas muaj peev xwm ncav cuag ib txoj hlua nyias zoo li cov qauv tsis muaj kev tawg. Nyob rau hauv chav tsev kub, npib tsib xee muaj cov khoom sib nqus. Tsis tas li ntawd, cov hlau no muaj txiaj ntsig zoo hauv kev tsim cov alloys sib txawv.
Dab tsi yog Silver?
Nws yog ib qho tshuaj lom neeg muaj tus lej atomic 47 thiab cov cim tshuaj Ag. Lub cim Ag los ntawm lo lus Latin Argentum txhais tau tias nyiaj. Cov hlau yog heev unreactive; yog li ntawd, nws tshwm sim nyob rau hauv tej yam li ib tug ntshiab hlau. Ntxiv mus, nws muaj ib tug yam ntxwv, lustrous tsos. Qee cov ntsiab lus tseem ceeb ntawm cov nyiaj muaj xws li hauv qab no:
- Atomic naj npawb=47
- Atomic mass=107.86 amu
- Electron configuration=[Kr] 4d105s1
- Lub cev lub cev=khoom ntawm chav sov
- Position in the periodic table=pawg 11, lub sij hawm 5 (d block)
- Melting point=961.7oC
- Boiling point=2162 °C
- Isotopes=Ag-107 thiab Ag-109 yog cov isotopes tseem ceeb
Daim duab 2: Ib Nyiaj Bar
Nyiaj yog corrosion resistant vim nws unreactive xwm. Ntxiv mus, nws muaj ntau daim ntawv thov nyob rau hauv zus tau tej cov hniav nyiaj hniav kub, electronics (los ua conductors thiab electrodes), catalysis (nws yog ib tug zoo catalyst rau oxidation tshua), nyiaj nanoparticles, thiab lwm yam.
Qhov txawv ntawm Nickel thiab Nyiaj yog dab tsi?

Summary – Nickel vs Silver
Qhov sib txawv tseem ceeb ntawm npib tsib xee thiab nyiaj yog tias lub ntsiab lus melting ntawm npib tsib xee yog nyob ib puag ncig ob zaug siab dua qhov kub ntawm cov nyiaj. Txawm hais tias qhov sib txawv ntawm cov khoom siv tshuaj, ob qho no yog cov hlau tseem ceeb uas muaj qhov zoo sib xws.
