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.
