Zoo sib xws nruab nrab hlau thiab tsis yog hlau yog: ob hlau thiab tsis yog hlau yog cov khoom. Ob leeg muaj tib lub qauv atomic. Ob leeg sib koom electrons los ua molecules.

Cov lus nug tseem yog, qhov zoo sib xws thiab qhov sib txawv ntawm cov hlau thiab nonmetals yog dab tsi?

Thaum hlau yog cov conductors zoo ntawm hluav taws xob thiab cua sov, cov hlau tsis muaj hlau yog cov conductors tsis zoo. Tsis zoo li cov hlau tsis muaj hlau , hlau yog ductile, uas txhais tau hais tias lawv tuaj yeem ncab mus rau hauv cov xov hlau. Lwm tus qhov sib txawv ntawm cov hlau thiab cov hlau tsis yog hlau , yog tus qub muaj a nws yog xim hlau luster, thaum lwm tus tsis.

Tsis tas li ntawd, qhov zoo sib xws ntawm cov hlau nonmetals thiab metalloids yog dab tsi? Hauv kev sib piv nrog hlau *, metalloids cov khoom yuav ua tau ib tug conductor tab sis nyob rau hauv ib tug ncaj ncees yam nkaus xwb. Lawv kuj muaj qhov ntom ntom dua piv rau cov hlau tsis muaj hlau thiab muaj qhov zoo li hlau. Hauv sib piv , metalloids yog nkig ntau dua piv nrog hlau uas yog ductile thiab malleable (yog tias khov).

Kuj paub, dab tsi tsis yog hlau thiab hlau muaj nyob hauv?

Nonmetals . Nonmetals muaj cov khoom opposite cov ntawm cov hlau . Cov nonmetals yog nkig, tsis malleable los yog ductile, tsis zoo conductors ntawm ob qho tib si tshav kub thiab hluav taws xob, thiab zoo li yuav tau txais electrons nyob rau hauv cov tshuaj tiv thaiv.

Dab tsi yog nonmetals muaj sib xws?

Cov khoom ntawm Nonmetals Nonmetals muaj siab ionization zog thiab electronegativities. Lawv yog feem ntau tsis zoo conductors ntawm tshav kub thiab hluav taws xob. Khoom nonmetals yog feem ntau brittle, nrog me me los yog tsis muaj xim hlau luster. Feem ntau nonmetals muaj muaj peev xwm nce electrons yooj yim.
