Native Elements . Minerals uas yog tsim los ntawm atoms los ntawm ib leeg keeb raug hu ua haiv neeg . Hauv pawg hlau, lub npib tsib xee yog qhov loj tib yam li hlau (muaj tib lub atomic radii) thiab tuaj yeem hloov tau qee qhov ntawm nws. Qhov no yog hu ua solid-solution.
Yog li ntawd, dab tsi yog suav hais tias yog ib haiv neeg?
Native keeb minerals yog cov cov ntsiab lus uas tshwm sim nyob rau hauv qhov nyob rau hauv uncombined daim ntawv nrog ib tug txawv mineral qauv. Cov chav kawm muaj xws li hlau thiab intermetallic cov ntsiab lus , ib txwm tshwm sim alloys, semi-metals thiab non-metals.
Qhov thib ob, puas yog pob zeb diamond ib txwm nyob? Cov haiv neeg suav nrog pob zeb diamond , Cr, W, Co, Si, Al, Ta and Fe; carbide minerals yog WC thiab SiC; PGE minerals yog OsIr, OsIsRu, thiab FePt; hlau alloys yog Fe–Cr–Ni, Fe–Al–Si, Ni–Cu, Ag–Au, Ag–Sn, Fe–Si, Fe–P thiab Ag–Zn–Sn; oxide minerals yog NiCrFeO, TiO2, Si-rutile, corundum, wüstite, ferrite, Fe2O3, ZnO, MnO and ib
Xav txog qhov no, puas yog pyrite Ib haiv neeg keeb kwm?
Rau kev kho mob tag nrho, saib cov ntxhia: Native ntsiab . Cov no haiv neeg feem ntau muab faib ua peb pawg-namely, hlau (platinum, iridium, osmium, hlau, zinc, tin, kub, nyiaj, tooj liab, mercury, lead, chromium); semimetals (bismuth, antimony, arsenic, tellurium, selenium); thiab nonmetals (sulfur, carbon).
Dab tsi yog qhov tsis yog haiv neeg?
Cov hlau tsis tshua muaj hauv ntiaj teb yog cov cov ntsiab lus uas ua tsis yog muaj nyob rau hauv haiv neeg daim ntawv. Aluminium - Al. Bismuth - Ib. Cadmium - Cd. Chromium - Cr.

Puas yog cov lej ib txwm muaj qee zaum lossis tsis muaj tus lej sib piv?
1.5 yog tus lej rational uas tuaj yeem sau tau li: 3/2 qhov twg 3 thiab 2 ob leeg yog tus lej. Ntawm no tus lej rational 8 yog tus lej, tab sis tus lej rational 1.5 tsis yog tus lej li 1.5 tsis yog tus lej tag nrho. Yog li peb tuaj yeem hais tias Tus lej rational yog ib qho integer qee zaum tsis tas li. Yog li ntawd, tej zaum lo lus teb raug yog
Puas yog npib tsib xee ci los yog npub?
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 txheej oxide tiv thaiv kev ua haujlwm ntxiv ntawm kev ua haujlwm Nws yog tus neeg xyuas pib ntawm hluav taws xob thiab cua sov
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
Cov xim ntawm npib tsib xee yog dab tsi?
Nyiaj dawb
Puas yog ib yam khoom uas muaj zog ib txwm muaj lub zog?
Ch 8 Xav & Piav Cov Lus Teb: Yog, ib yam khoom uas muaj zog ib txwm muaj zog. Yog tias cov khoom muaj lub zog (mv) nws yuav tsum txav mus, thiab yog tias nws txav mus, nws muaj lub zog kinetic.Tsis yog, ib qho khoom uas muaj lub zog tsis tas yuav muaj lub zog. Txij li cov khoom no lub nrawm = 0, nws lub zog yog xoom
