Ammonia yog covalent compound vim yog qhov sib txawv ntawm electronegativity ntawm hydrogen thiab nitrogen atom piv txwv li; 0.9 ua. Nitrogen thiab hydrogen atoms qhia lawv cov electrons rau ib leeg los tsim ib daim ntawv cog lus uas ua rau muaj covalent NH3 compound.
Vim li cas NH3 yog covalent compound?
Ammonia, lossis NH3, yog cov khoom sib txuas sib txuas ua ke vim nws cov atoms tsis sib txawv txaus hauv electronegativity los tsim …
Koj faib cov ionic lossis covalent compound li cas?
Ionic tebchaw yog (feem ntau) tsim thaum hlau reacts nrog ib tug nonmetal(los yog ib tug polyatomic ion). Covalent compounds yog tsim thaum ob nonmetals react nrog ib leeg. Txij li thaum hydrogen yog nonmetal, binary compounds uas muaj hydrogen kuj feem ntau covalent compounds.
Yuav ua li cas daim ntawv cog lus nyob rau hauv NH3?
NH3 muaj covalent ib daim ntawv cog lus ntawm nws cov nitrogen thiab hydrogen atoms. Daim ntawv cog lus cog lus txhais tau tias N thiab H atoms sib koom valence electrons thaum tsim…
Yog NaCl covalent lossis ionic?
Ionic daim ntawv cog lus feem ntau tshwm sim ntawm cov hlau thiab cov hlau tsis muaj hlau. Piv txwv li, sodium (Na), hlau, thiab chloride (Cl), nonmetal, tsim ib daim ntawv cog lus ionic los ua NaCl. Hauv daim ntawv cog lus covalent, atoms daim ntawv cog lus los ntawm kev sib koom electrons.
