Ions tshwm sim los ntawm atoms lossis molecules uas tau txais lossis poob ib lossis ntau dua valence electrons, muab lawv qhov zoo lossis tsis zoo. nqi . Cov uas muaj qhov tsis zoo nqi hu ua anions thiab cov uas muaj qhov zoo nqi hu ua cations.
Cov lus nug tseem yog, dab tsi yog anion?
Ib anion yog hom ionic nrog rau tus nqi tsis zoo Cov tshuaj lom neeg yuav yog ib qho atom lossis ib pawg ntawm atoms. Ib anion yog attracted rau lub anode hauv electrolysis. Anions feem ntau loj dua cations (zoo them ions) vim tias lawv muaj cov hluav taws xob ntxiv nyob ib puag ncig lawv.
Tsis tas li ntawd, ib qho piv txwv ntawm anion yog dab tsi? Anion : Thaum lub atom tau txais electron(s), nws yuav ua tsis zoo them ion hu ua anion . Piv txwv : chlorine tau txais ib qho hluav taws xob los tsim cov tshuaj chloride ion (Cl-), xws li hauv NaCl.
tus nqi ntawm AS yog dab tsi?
Table of Common Element Charges
| Tus lej | Element | Them nqi |
|---|---|---|
| 30 | zinc | 2+ |
| 31 | gallium | 3+ |
| 32 | germanium | 4-, 2+, 4+ |
| 33 | arsenic | 3-, 3+, 5+ |
Anion ua dab tsi rau lub cev?
Anions stabilize cov ntshav siab, thaum cation nce ntshav siab. Anions txo cov ntshav qab zib, thaum cation nce ntshav qab zib. Anions ntxiv dag zog rau lub plawv dhia, thaum cation tsis muaj zog nws.

Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Yuav ua li cas koj thiaj nrhiav tau tus nqi siab tshaj plaws ntawm lub quadratic muaj nuj nqi?
Yog tias koj tau txais cov mis y = ax2 + bx + c, ces koj tuaj yeem pom tus nqi siab tshaj plaws uas siv cov mis max = c- (b2 / 4a). Yog tias koj muaj qhov sib npaug y = a (x-h) 2 + k thiab theatrem tsis zoo, ces qhov siab tshaj plaws yog k
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
Txhais li cas los ntawm tus nqi ntws ntawm tus nqi hluav taws xob?
