Cov hlau yog nyob rau sab laug ntawm txoj kab (tshwj tsis yog hydrogen, uas yog nonmetal), cov nonmetals yog nyob rau sab xis ntawm txoj kab, thiab cov ntsiab tam sim ntawd nyob ib sab ntawm txoj kab yog cov metalloids.
Hlau , Metalloids, thiab Nonmetals.

Yog li ntawd, mg yog hlau lossis nonmetal?
Cov tub ntxhais kawm pawg tau faib magnesium , zinc , hlau thiab tin li hlau ; sulfur ua nonmetal thiab silicon thiab carbon li metalloids. Cov pa roj carbon ua hluav taws xob thiab tsis muaj cov yam ntxwv luster.
sulfur puas yog hlau? Sulfur yog tsis yog- hlau vim nws tsis muab tso rau hauv hlau pab pawg nyob rau hauv lub sij hawm. Sulfur tau piav raws li qhov tsis yog- hlau txij li nws yog ntseeg tau nrog 3 lub cev khoom sau tseg rau nonmetals.
Yog li ntawd, yog Cl A hlau?
Nws tau muab tso rau hauv lub sijhawm thib peb thiab 7A pab pawg. Nws yog chemical symbol yog Cl . Chlorine tuaj yeem sawv cev rau hauv lub rooj zaum ntu raws li hauv qab no: Chlorine yog tam sim no ntawm txoj cai ntawm metalloids, yog li ntawd, nws tuaj yeem xaus lus tias tshuaj chlorine yog tsis yog- hlau.
Vim li cas sodium yog hlau?
Sodium yog cov khoom siv tshuaj nrog lub cim Na (los ntawm Latin natrium) thiab atomic tooj 11. Sodium yog alkali hlau , nyob rau hauv pawg 1 ntawm lub sij hawm lub sij hawm, vim hais tias nws muaj ib tug tib electron nyob rau hauv nws lub plhaub sab nrauv, uas nws yooj yim pub dawb, tsim ib tug zoo ion-the Na.+ cation. Nws tsuas yog ruaj khov isotope yog 23Na.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Puas yog hlau yog hlau muaj zog?
Hlau yog cov khoom siv tshuaj thiab cov hlau. Nws yog qhov thib ob feem ntau hlau nyob hauv ntiaj teb, thiab feem ntau siv hlau. Nws ua rau ntau lub ntiaj teb lub hauv paus, thiab yog plaub feem ntau ntawm lub ntiaj teb lub pob zeb. Cov hlau siv ntau heev vim nws muaj zog thiab pheej yig
Cov hlau nplaum puas yuav lo rau galvanized hlau?
"Galvanized" tsuas yog txhais tau hais tias muaj cov zinc txheej sab nraud ntawm cov Hlau. Yog hais tias cov hlau ismagnetic pib nrog, ces nws tseem yuav sib nqus tom qab galvanizing. Txij li feem ntau tsis muaj laj thawj rau galvanizestainless hlau, cov lus teb yuav luag ib txwm "yog, galvanized steel yog sib nqus"
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Puas yog alkali hlau thiab alkaline ntiaj teb hlau zoo ib yam?
Valance: Tag nrho cov alkali hlau muaj ib qho hluav taws xob nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Yuav kom ua tiav cov kev teeb tsa muaj txiaj ntsig zoo, cov hlau alkali yuav tsum poob ib lub tshuab hluav taws xob (valence yog "ib"), thaum alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob")
