Lub npe poly- txhais tau tias "ntau," hauv Greek, tab sis txawm tias ions ntawm ob lub atom feem ntau hu ua polyatomic. Piv txwv li: Carbonate (CO 3 2-), sulphate (SO 42-), nitrate - TSIS MUAJ 3 - thiab hydroxide ions hydroxide ions Hydroxide yog ib qho diatomic anion nrog tshuaj formula OH- Nws muaj cov pa oxygen thiab hydrogen. atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa ib qho hluav taws xob tsis zoo. Nws yog ib qho tseem ceeb tab sis feem ntau me me ntawm cov dej. Nws ua haujlwm raws li lub hauv paus, ligand, nucleophile, thiab catalyst. https://en.wikipedia.org › wiki › Hydroxide
Hydroxide - Wikipedia
OH- yog txhua yam polyatomic ions.
Dab tsi yog polyatomic ions muab piv txwv?
Polyatomic ions yog ions uas muaj ntau dua ib lub atom Piv txwv li, nitrate ion, NO3-, muaj ib lub nitrogen atom thiab peb oxygen atoms. Cov atoms nyob rau hauv ib tug polyatomic ion feem ntau yog covalently bonded rau ib leeg, thiab yog li ntawd nyob ua ke raws li ib tug, them unit. Txoj Cai 1.

Dab tsi yog polyatomic ions? Muab ob qho piv txwv
- Polyatomic atoms yog pawg ntawm atoms uas muaj nuj nqis rau lawv.
- Vim li no ions raug them cov khoom.
- Example:
- Sulphate ion --- SO4⁻²
- sulphate ion muaj atoms ntawm leej faj thiab oxygen atoms nrog tus nqi ntawm -2.
- Carbonate Ion - CO3⁻²
Dab tsi yog polyatomic ions muab ob qho piv txwv Brainly?
Polyatomic ions raws li lub npe qhia yog cov ions uas muaj ntau tshaj ib lub atom. Cov atoms yuav zoo ib yam lossis sib txawv. Piv txwv li: Ammonium ions, Carbonate ions, cyanide ions, chlorite ions yog qee qhov piv txwv ntawm polyatomic ions.
Dab tsi yog polyatomic ions Class 9?
Polyatomic ions: Cov ions uas tau tsim los ntawm pawg ntawm cov atoms koom nrogyog hu ua polyatomic ions. Cov ions tseem hu ua polyatomic ions. Rau eg. Ammonium ion NH4 +, yog ib qho kev sib xyaw ion uas yog tsim los ntawm ob hom atoms koom ua ke nitrogen thiab hydrogen.
