Antimony yog ib yam tshuaj muaj cim Sb thiab atomic tooj 51. Classified as a metalloid, Antimony yog ib qho khoom ntawm chav tsev kub.
Vim li cas antimony yog metalloid?
A series ntawm rau lub ntsiab hu ua metalloids cais cov hlau los ntawm nonmetals nyob rau hauv lub sij hawm lub sij hawm. Cov metalloids yog boron, silicon, germanium, arsenic, antimony, thiab tellurium. … Lawv yog semiconductors vim lawv cov electrons nruj nreem khi rau lawv cov nuclei ntau dua li cov hlau conductors
hom hlau twg yog antimony?
Antimony yog ib qho semi-metal Hauv nws daim ntawv hlau nws yog silvery, tawv thiab nkig. Antimony yog siv hauv kev lag luam hluav taws xob los ua qee yam khoom siv semiconductor, xws li infrared detectors thiab diodes. Nws yog alloyed nrog txhuas lossis lwm yam hlau los txhim kho lawv cov hardness thiab lub zog.
