Hauv sib piv , metalloids yog nkig ntau dua piv nrog hlau uas yog ductile thiab malleable (yog tias khov). Hauv kev sib piv nrog cov hlau tsis muaj hlau , metalloids tuaj yeem yog cov insulators thiab nkig (yog tias cov hlau tsis muaj hlau yog nyob rau hauv daim ntawv khov). Hauv sib piv , cov hlau tsis muaj hlau tsis yog lustrous li metalloids thiab feem ntau ntawm cov cov hlau tsis muaj hlau yog gases.
Yog li ntawd, dab tsi yog qhov zoo sib xws ntawm cov hlau thiab nonmetals?
Hlau zoo li muaj zog thiab conductive, thiab muaj cov ntsiab lus melting siab. Txawm li cas los xij, zoo li nonmetals , lawv cov ntaub ntawv tshwm sim raws li ib tug sib txawv ua ke ntawm electrons, protons thiab neutrons. Tag nrho cov ntsiab lus, hlau los yog lwm yam, tuaj yeem hloov lub xeev lossis cuam tshuam.
Tsis tas li ntawd, cov nonmetals muaj dab tsi zoo 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.
Ua li no, cov hlau nonmetals thiab metalloids muaj dab tsi?
Raws li piv rau hlau , lawv muaj tsawg ceev thiab yuav yaj ntawm qhov kub thiab txias. Cov duab ntawm nonmetals tsis tuaj yeem hloov tau yooj yim vim lawv nkig thiab yuav tawg. Cov ntsiab lus ntawd muaj cov khoom ntawm ob qho tib si hlau thiab nonmetals hu ua metalloids . Lawv ua tau yuav ci los yog npub thiab lawv cov duab hloov tau yooj yim.
Dab tsi yog qhov zoo sib xws ntawm cov hlau thiab metalloids?
Hauv kev sib piv nrog hlau *, metalloids cov khoom tuaj yeem ua tus neeg xyuas pib tab sis hauv a ncaj ncees nkaus xwb. Lawv kuj muaj qhov ntom ntom dua piv rau cov tsis- 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).

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov zoo sib xws ntawm cov hlau thiab nonmetals?
Qhov zoo sib xws ntawm cov hlau thiab cov hlau tsis yog: Cov hlau thiab cov hlau tsis yog cov khoom. Ob leeg muaj tib lub qauv atomic. Ob leeg sib koom electrons los ua molecules
