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
