A polyatomic ion , kuj hu ua molecular ion , yog them tshuaj hom ( ion ) tsim los ntawm ob los yog ntau tshaj atoms covalently bonded los yog ntawm ib tug metalcomplex uas yuav suav tau tias yog ua raws li ib tug unit. Theprefix poly- txhais tau tias "ntau," hauv Greek, tab sis txawm ions ntawm twoatoms feem ntau hu ua polyatomic.
Tsuas yog li ntawd, qhov piv txwv polyatomic ion yog dab tsi?
Polyatomic ions yog ions uas muaj ntau tshaj ib tug atom. Rau piv txwv , nitrate ion , TSIS MUAJ3-, muaj ib tug nitrogen atom thiab threeoxygen atoms. Cov atoms hauv a polyatomic ion yog feem ntau covalently bonded rau ib leeg, thiab yog li ntawd nyob ua ke asingle, them unit.
Kuj Paub, cov cai rau npe polyatomic ions yog dab tsi? Txoj cai 1. Lub cation yog sau ua ntej ntawm lub npe; lub anion yog sau thib ob nyob rau hauv lub npe. Txoj cai 2. Thaum theformula chav tsev muaj ob lossis ntau dua ntawm tib yam polyatomicion , uas ion yog sau nyob rau hauv kab lus nrog cov subscript sau sab nraum cov kab lus.
Kuj tseem yuav paub, qhov txawv ntawm qhov sib xyaw thiab polyatomic ion yog dab tsi?
Cov tshuaj yog cov koom haum uas feem ntau tuaj yeem cais tawm raws li lawv tau sau yam tsis xav tau lwm yam. Lawv tuaj yeem tsim los ntawm ions , molecules, molecular ions , zwitterions, hlau atoms, thiab lwm yam. Ions yog chargedspecies. Ua ke nrog counterions ntawm opposite nqi, lawv tuaj yeem ua tau tshuaj sib xyaw.
Puas yog HCl yog polyatomic ion?
HCl , uas muaj cov anion chloride, hu ua hydrochloric acid . HNO3, uas muaj polyatomicion nitrate, hu ua nitric acid.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Lub npe ntawm polyatomic ion mno4 yog dab tsi?
Cov cim thiab cov npe ntawm qee yam Polyatomic Ions thiab Ib Molecule NH4 + ammonium ion OH- PO33- phosphite ion MnO4- Cov qauv thiab cov npe rau qee cov kua qaub (tag nrho cov npe yuav tsum muaj cov kua qaub ntxiv) H2SO4 sulfuric H3PO4
Cov mis rau polyatomic ion carbonate yog dab tsi?
Nqe lus piav qhia: Carbonate Ion yog polyatomic ion
Dab tsi ntawm daim ntawv cog lus tuav cov atoms ua ke hauv polyatomic ions?
Covalent bonding yog hom kev sib cog lus uas tuav ua ke cov atoms hauv polyatomic ion. Nws yuav siv ob lub electrons los ua covalent daim ntawv cog lus, ib qho los ntawm txhua qhov sib txuas atom. Lewis dot structures yog ib txoj hauv kev los sawv cev li cas atoms tsim covalent bonds
Dab tsi yog cov lej ntawm oxidation hauv polyatomic ion?
Cov lej ntawm cov lej oxidation hauv polyatomic ion yog sib npaug rau tus nqi ntawm cov ion. Tus lej oxidation ntawm sulfur atom hauv SO42- ion yuav tsum yog +6, piv txwv li, vim tias cov lej ntawm cov oxidation ntawm cov atoms hauv cov ion no yuav tsum sib npaug -2
