Nws yog cov pa roj, raws li nws muaj nyob rau hauv cov txheej txheem cov khoom siv roj, nws muaj noshine, tsis tuaj yeem ua hluav taws xob lossis. Ua tsis zoo, tib yam nrog cua sov. Chemically nws tuaj yeem oxidize thiab txo qis thaum hlau tsuas yog oxidize, thiab nitrogen oxides react nrog dej los ua acids, thaum hlau ua bases..
Tsis tas li ntawd, puas yog nitrogen yog hlau lossis tsis yog hlau?
Cov khoom tsis yog hlau lossis cov hlau tsis yog hlau; hydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorus (P), sulfur ( sulfer ) (S), selenium (Se), (Uuo tej zaum yuav nyob ntawm no) thiab cov pa roj carbon monoxide tsim ib pawg me me nrog cov kauj ruam zoo li cov qauv ntawm sab laug ntawm lub rooj zaum ( hydrogen ua qhov txawv
Ib sab saum toj, yog vim li cas aluminium yog hlau thiab nitrogen tsis yog? Teb: Nitrogen : Tsis yog - hlau = Lawv yog cov hluav taws kub thiab hluav taws xob tsis zoo, lawv yog cov khoom tawg yooj yim, tsis yog ductile nyob rau hauv lawv cov khoom muaj zog - lawv tsis tuaj yeem dov mus rau hauv cov xov hlau los yog pounded rau hauv nplooj ntawv. Aluminium : Hlau = Muab cov khoom tsis tshua muaj txiaj ntsig.
Ib yam li ntawd, nws raug nug, vim li cas nitrogen tsis yog hlau?
Nitrogen yog a nonmetal . Nitrogen cov ib txwm gaseous daim ntawv thiab nws cov high electronegativity yog ob yam yooj yim ntawm nonmetals . Tsis tas li ntawd, qhov tsis muaj zog
Puas yog Potassium yog hlau lossis nonmetal?
Lub ntsiab poov tshuaj yog a hlau thiab nws belongs rau Pawg 1, uas muaj cov alkali hlau . Potassium yog mos thiab silver-dawb nyob rau hauv tsos. Nws cov cim tshuaj yog K, thiab nws muaj tus lej atomic ntawm 19.
Pom zoo:
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
Qhov laj thawj twg zoo tshaj plaws piav qhia vim li cas cov hlau tsis muaj ductile es tsis nkig?
Cov hlau yog ductile es tsis txhob nkig vim tias lawv muaj cov ntawv cog lus hloov tau. Ductility txhais tau hais tias muaj peev xwm ntawm cov hlau los kos rau hauv cov xov hlau. Cov hlau muaj cov khoom sib txuas yooj yim. Qhov kev hloov pauv no tso cai rau lawv ua cov khoom siv
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Vim li cas tus choj ntsev siv tsis yog hlau?
Ntsev choj Saib yog vim li cas ib daim hlau tsis tuaj yeem siv los ntawm kev siv ntsev? Tus choj ntsev tso cai ntws ntawm ions (them nqi) los tiv thaiv tus nqi tsim tawm hauv cov kev daws teeb meem ionic. Ib txoj hlua yuav tsis ua li ntawd
Vim li cas carbon tsis yog hlau?
Cov pa roj carbon monoxide yog cov hlau tsis muaj hlau, thiab cov hlau tsis muaj hlau tsis zoo yog cov khoom siv hluav taws xob tsis zoo vim tias cov qauv ntawm cov khoom siv yog ib qho 'kev npaj kaw.' Silicon andgermanium uas tseem nyob rau hauv pab pawg IVA yog semi-conductors thiab raug cais raws li metalloids
