Aluminium oxide yog ionic compound , tab sis aluminium chloride tsuas yog ionic nyob rau hauv cov khoom hauv lub xeev ntawm qhov kub thiab txias. Thaum kub dua nws ua covalent.
Ua li no, puas yog Al2O3 ionic lossis covalent?
Raws li nws qhov sib npaug, Al2O3 yog me ntsis nore ionic tshaj covalent . Cov nqi siab dua ntawm Al thiab O ua rau lawv txoj kev sib raug zoo ntau dua covalent thiab nrog siab dua Coulombic attraction ntawm qhov zoo thiab qhov tsis zoo ions cov ntawm ib tug binary compound nrog ions ntawm cov nqi qis (piv txwv li CaF2, NaCl).
Ib yam li ntawd, puas yog aluminium oxide ib qho ionic compound? Cov compound yog ionic nyob rau hauv qhov, vim hais tias nws muaj ib tug hlau ( aluminium ) thiab tsis yog hlau (oxygen). Ionic compounds tshwm sim ntawm cov hlau thiab cov hlau tsis yog hlau thiab koom nrog kev sib pauv ntawm electrons ntawm ob lub atoms. Qhov no txhais tau tias cov tshuaj formula rau aluminium oxide tsuas yog Al2 O3.
Ib tug kuj yuav nug, yog Al2O3 yog ionic khoom?
Al2O3 yog ionic vim yog cov txheeb ze ntawm cov pa oxygen thiab txhuas thiab polarizing zog ntawm Al, (vim peb paub tias txhuas muaj tus nqi ntawm +3, muab peb electrons) nyob rau hauv cov ntaub ntawv ntawm Al2Cl6 & AlCl3, nws zoo li yuav covalent vim zoo sib xws xws li txiv tsawb bonding & loj lub vojvoog ntawm Cl (hauv compression rau oxygen).
Hom tshuaj twg yog Al2O3?
Aluminium oxide
Pom zoo:
Puas yog o3 covalent lossis ionic?
Lub O3 molecule muaj peb cov pa oxygen atoms, ib qho kev sib koom ua ke covalent daim ntawv cog lus thiab ib daim ntawv cog lus ob npaug. Ob lub O-O uas sib koom ua ke ob qho kev sib cog lus yog nonpolar vim tias tsis muaj electronegativity ntawm cov atoms ntawm tib lub caij, sib koom tib cov xov tooj ntawm electrons
Puas yog aluminium nitrite ionic lossis covalent?
Aluminium nitrite muaj cov aluminium cation Al3+ thiab polyatomic nitrite anion NO − 2. Txij li thaum lub ionic compound yuav tsum nyob nruab nrab, tus naj npawb ntawm txhua ion yuav tsum ua rau tag nrho cov nqi ntawm xoom
Puas yog potassium phosphide ionic lossis covalent?
Txhawm rau sib npaug qhov no (kom tus nqi ntawm cov ntsev nruab nrab peb xav tau 3 poov tshuaj rau txhua 1 phosphideanion. Qhov no muab ib chav tsev ntawm (K +) 3 (P-), uas tau qhia hauv Lewis qauv. Tsis tas li ntawd, vim qhov no yog ib qho ionic compound, tsis muaj kev sib txuas ncaj qha tshwm sim
Puas yog aluminium bromide ionic lossis covalent?
Lesson Summary Aluminium bromide yog ib qho ionic compound uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm txhuas nrog kua bromine. Aluminium atoms muab peb lub electrons ua rau Al + 3 thiab bromine atoms nce ib lub electron txhua qhov ua rau Br-1
Koj tuaj yeem sim ua li cas thiaj txiav txim siab seb qhov sib xyaw puas yog ionic lossis covalent?
Muaj ob peb txoj hauv kev los txiav txim siab seb daim ntawv cog lus yog ionic lossis covalent. Los ntawm kev txhais, daim ntawv cog lus ionic yog nruab nrab ntawm cov hlau thiab cov hlau tsis muaj hlau, thiab covalent daim ntawv cog lus yog nruab nrab ntawm 2 nonmetals. Yog li koj feem ntau tsuas yog saib ntawm lub rooj zaum thiab txiav txim siab seb koj cov khoom puas yog ua los ntawm cov hlau / nonmetal lossis tsuas yog 2 nonmetals xwb
