Metals vs Nonmetals
Ob qho tib si hlau thiab nonmetals tej zaum yuav yog ib feem ntawm lub sij hawm lub sij hawm tab sis muaj ntau qhov sib txawv ntawm hlau thiab nonmetals nyob rau hauv cov tshuaj thiab lub cev ua-up. Feem ntau ntawm cov ntsiab lus nyob rau hauv lub rooj zaum yog hlau thiab tsuas yog ob peb yog nonmetals. Cov ntsiab lus no yog teem rau hauv lub rooj los ntawm lawv cov qauv hluav taws xob. Nws yeej ib txwm pab tau kom paub qhov txawv ntawm ob qho tib si kom nkag siab lawv kom meej.
Dab tsi yog hlau?
Hlau yog cov khoom hluav taws xob zoo. Lawv ci ntsa iab thiab yoog raws. Cov hlau feem ntau tuaj yeem raug ntaus rau hauv cov ntawv nyias lossis tuaj yeem ua rau cov hlau nyias nyias. Cov hlau zoo li xoob electrons thaum lawv raug hloov tshuaj. Cov hlau kuj tuaj yeem ua tus neeg sawv cev zoo. Mercury tsuas yog cov hlau uas yog kua hauv chav tsev kub, feem ntau cov hlau yog lwm yam khoom.
Nonmetals yog dab tsi?
Nonmetals ntawm qhov tod tes, sib txawv ntawm cov duab thiab qhov ntau thiab tsawg. Lawv kuj tuaj ntawm cov xim sib txawv. Lawv nkig thiab tuaj yeem ua tau ob qho tib si tawv thiab muag. Nonmetals tsis muaj peev xwm ua tau hluav taws xob zoo. Lawv yog cov tshuaj oxidizing zoo thiab tuaj yeem ua kua, khoom lossis roj ntawm chav tsev kub. Thaum cov hlau sib xyaw los yog ua rau cov hlau tsis yog hlau, cov hlau tsis yog hlau nce electrons yog li ua anions.
Dab tsi yog qhov txawv ntawm Hlau thiab Nonmetals?
Ob leeg, hlau thiab nonmetals, muaj qhov sib txawv ntawm cov tshuaj thiab lub cev.
Hlau yog cov khoom siv hluav taws xob zoo thiab cua sov thiab thaum raug tshuaj lom neeg hloov pauv lawv xoob electrons thiab ua cations. Tsis tas li ntawd, cov hlau yog cov khoom nyob rau hauv chav tsev kub thiab hloov tau thiab stretchable. Feem ntau, lawv muaj ib lossis ob xim uas feem ntau yog nyiaj hauv ntxoov ntxoo.
Tsis yog-hlau, ntawm qhov tod tes, tsis yog cov khoom siv ntawm qhov no thiab nce electrons thiab tig mus rau hauv anions thaum lawv hloov pauv tshuaj. Tsis tas li ntawd, cov hlau tsis yog hlau tuaj yeem yog cov khoom, kua, lossis roj thiab tuaj yeem ua ntau yam xim. Lawv yog nkig thiab tsis stretchable los yog inflexible yog hais tias lawv nyob rau hauv lawv cov ntaub ntawv khoom.
In luv: Hlau vs Nonmetals• Tshuaj lom neeg yog cais raws li hlau thiab tsis yog hlau los yog metalloids raws li lawv lub cev thiab tshuaj. • Cov hlau yog cov khoom siv hluav taws xob zoo thiab cua sov thaum cov hlau tsis zoo hauv qhov ntawd. • Cov hlau yog yoog raws thiab yoog raws thaum cov hlau tsis yog hlau. • Cov hlau feem ntau tuaj hauv cov ntaub ntawv zoo thaum cov hlau tsis yog hlau tuaj yeem yog cov khoom, kua lossis roj. • Cov hlau muaj ib qho luster lossis ci thaum cov hlau tsis yog npub; nonmetals txawm li cas los xij, tuaj hauv cov xim sib txawv. • Cov hlau feem ntau tsim cov oxides yooj yim thaum cov nonmetals yog cov oxidizing zoo. • Cov hlau thaum raug tshuaj hloov pauv xoob electrons thaum nonmetals nce electrons thiab tig mus ua anions. • Melting point thiab boiling point ntawm nonmetals yog ho qis dua piv rau cov hlau, Carbon yog zam. • Nonmetals yog cov carbon, hydrogen, nitrogen, phosphorous, oxygen, sulfur, selenium, halogens thiab noble gases. |
