Nickel yog ib qho nyuaj, malleable, ductile hlau. Nws yog ci iab nyiaj hlau nrog me ntsis kub tinge uas yuav siv sij hawm ahigh polish thiab resists corrosion. Lub caij ua oxidize, tab sis cov oxide txheej tiv thaiv kev ua haujlwm ntxiv ntawm passivation Nws yog tus neeg xyuas pib ntawm hluav taws xob thiab cua sov.
Hauv qhov no, yog Silicon ci los yog npub?
Metalloids yog cov khoom uas tuaj yeem ua tau ci los yog npub . Lawv ua hluav taws xob thiab cua sov zoo dua cov nonmetals tab sis tsis zoo li hlau. Silicon eg muaj a ci iab metallic luster thiab yog ib tug nruab nrab neeg xyuas pib Tab sis nws yog nkig andshatters thaum koj ntaus nws nrog rauj.
Ib sab saum toj no, yog tus txiv neej nickel tsim los yog ntuj? Nickel Hlau - Qhov Tseeb. Nickel yog a ib txwm tshwm sim, lustrous, silvery-dawb metallicelement. Nws yog lub thib tsib feem ntau nyob rau hauv lub ntiaj teb thiab tshwm simextensively nyob rau hauv lub ntiaj teb crust. Txawm li cas los xij, feem ntau ntawm cov npib tsib xee yog tsis nkag mus rau hauv lub hauv paus ntawm lub ntiaj teb.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi ua rau nickel tshwj xeeb?
Nws yog ntseeg hais tias qhov no loj deposit ntawm npib tsib xee ore yog tshwm sim los ntawm ib qho kev cuam tshuam ntawm lub hnub qub qub. Nickel yog harard, corrosion resistant hlau. Nickel yog alloyed nrog rau lwm cov hlau los txhim kho lawv lub zog thiab tiv thaiv corrosion. Nickel yog alloyed nrog steel rau ua armor phaj, vaults thiab tshuab qhov chaw.
Puas yog nickel malleable?
Nickel yog ib tug silvery dawb hlau uas siv highpolish. Nickel nyuaj, ductile , tuaj yeem , thiab ferromagnetic. Nws yog ib tug ncaj ncees conductor ntawm tshav kub thiab hluav taws xob.

Puas yog npib tsib xee ib txwm muaj?
Native Elements. Minerals uas yog tsim los ntawm atoms los ntawm ib lub ntsiab lus raug xa mus rau cov ntsiab lus ib txwm muaj. Hauv pawg hlau, cov khoom nickel yog tib yam li hlau (muaj tib lub atomic radii) thiab tuaj yeem hloov pauv rau qee qhov ntawm nws. Qhov no yog hu ua solid-solution
Puas yog Tin ci los yog npub?
Alpha-tin yog nkig, npub, powdery, semimetallic daim ntawv ntawm tin. Nws yog tsim thaum lub tin ntshiab heev txias. Beta-tin yog ib txwm ci, mos, conductive, metallic daim ntawv
Cov xim dab tsi yog npib tsib xee hydroxide?
Xiav thiab ntsuab yog cov yam ntxwv xim ntawm cov nickel compounds thiab lawv feem ntau hydrated. Nickel hydroxide feem ntau tshwm sim raws li cov muaju ntsuab uas tuaj yeem ua rau nag lossis daus thaum aqueous alkali ntxiv rau kev daws ntawm nickel (II) ntsev. Nws yog insoluble hauv dej tab sis dissolves nkag tau hauv cov kua qaub thiab ammonium hydroxide
