Thiab raws li lwm qhov kev xeem sau los ntawm cov tub ntxhais kawm hauv chem club, Sb2Te3 yog ionic , yog li txoj kab faib tsis yog hlau-nonmetal faib kab. Nws zoo li koj yuav tsum paub qhov txawv ntawm electronegativity lossis qee yam, uas lawv yeej tsis muab rau koj. AsI3 thiab Sb2Te3 muaj tseeb covalent , tshwj xeeb tshaj yog qhov thib ob.
Hauv qhov no, hom ntawv cog lus twg yog AsF5?
Nyob rau hauv AsCl3, ib tug molecule, lub arsenic atom qhia nws 3 unpaired 4p electrons nrog lub 3 chlorine atoms, tsim ib tug covalent. daim ntawv cog lus nrog rau txhua yam ntawm chlorine atoms. Hauv AsF5 , arsenic atom cov ntaub ntawv sp3d hybrid orbitals, txhua tus tuaj yeem ua ib qho kev sib tw daim ntawv cog lus nrog ib tug fluorine atom.
Tom qab ntawd, lo lus nug yog, yog AsCl3 yog ib qho ionic compound? Nyob rau hauv rooj plaub ntawm AlCl3, txawm tias nws zoo li ib qho ionic Cov tshuaj tiv thaiv ntawm ib qho txhuas thiab peb chlorine, nws tsis yooj yim li ntawd. Yog, nws tsis yog. Koj pom, nyob rau hauv cov ntaub ntawv ntawm ionic compounds , cov hlau poob electron thaum lub non-hlau txais cov electron.
Tom qab ntawd, tus qauv molecular ntawm arsenic pentafluoride yog dab tsi?
AsF5
Lub npe AsCl5 yog dab tsi?
Arsenic pentachloride | AsCl5 - PubChem.
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
