Raws li Mohs hardness scale, ib daim ntawv teev mos hlau muaj xws li txhuas, kub, nyiaj, tin, zinc, txhuas, thorium, tooj liab, tooj dag thiab tooj liab. Gallium kuj tseem yuav xav txog ib soft hlau , raws li nws melts ntawm 85.57 degrees Fahrenheit. Mercury yog a hlau uas yog kua ntawm chav tsev kub.

Tsis tas li ntawd, cov hlau twg yog mos tshaj plaws?

Cesium suav hais tias yog tus softest hlau , Lead tseem suav nrog cov softest hlau . Teb 3: Mercuryis kua (molten) ntawm chav tsev kub. Gallium, thaum khov (yog tias mos ) nyob rau hauv chav tsev kub, yog kua ntawm lub cev kub.

Tsis tas li ntawd, puas yog txhuas hlau mos? Ntshiab aluminium (99.996 feem pua) yog heev mos thiab qaug zog; kev lag luam aluminium (99 mus rau 99.6 feem pua ntshiab) nrog me me ntawm silicon thiab hlau yog tawv thiab muaj zog. Ductile thiab malleable heev, aluminium tuaj yeem kos rau hauv cov hlau los yog dov rau hauv cov ntawv ci nyias. Cov hlau tsuas yog kwv yees li ib feem peb li ntom li hlau lossis tooj liab.

Ntawm no, cov hlau mos thiab tawv yog dab tsi?

Hlau ions nrog lub siab tshaj plaws affinities rau nyuaj bases yog nyuaj acids, yog hlau ions nrog lub siab tshaj plaws affinity rau mos bases yog mos kua qaub.

Kub puas yog hlau mos?

Kub hu ua hnyav hlau vim nws qhov siab ceev, uas yog los ntawm qhov tseeb tias txhua tus ntawm nws cov atomsis hnyav heev. Piv txwv li, kub atoms slidepast ib leeg kuj yooj yim, uas ua rau cov metalsoft thiab maleable.

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

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb

Qhov twg yog qhov zoo dua qhov kev xaiv ntuj los yog kev xaiv dag Yog vim li cas?

Thaum lub sij hawm xaiv ntuj, hom ciaj sia thiab kev yug me nyuam txiav txim siab cov yam ntxwv. Txawm hais tias tib neeg tuaj yeem txhim kho lossis ua rau lub cev muaj peev xwm los ntawm kev xaiv kev yug me nyuam, qhov xwm txheej cuam tshuam nws tus kheej nrog cov yam ntxwv uas tso cai rau qhov zoo rau cov tsiaj muaj peev xwm ua phooj ywg thiab muaj sia nyob

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
