ionic nqi Cov hluav taws xob nqi ntawm ib qho ion, tsim los ntawm qhov nce (tsis zoo nqi ) los yog poob (positive nqi ) ntawm ib lossis ntau dua electrons los ntawm ib lub atom lossis pawg atoms.
Yog li ntawd, ionic nqi txhais li cas?
ionic nqi Cov hluav taws xob nqi ntawm ib ion , tsim los ntawm qhov nce (tsis zoo nqi ) los yog poob (positive nqi ) ntawm ib lossis ntau dua electrons los ntawm ib lub atom lossis pawg atoms.
Tsis tas li ntawd, 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+ |
Ib sab saum toj no, koj yuav nrhiav tau ionic nqi li cas?
Yuav nrhiav tau ionic nqi ntawm ib lub caij koj yuav tsum tau sab laj nrog koj Lub Sijhawm Table. Ntawm Lub Sijhawm Table hlau (pom nyob rau sab laug ntawm lub rooj) yuav zoo. Cov hlau tsis muaj hlau (pom nyob sab xis) yuav tsis zoo. Tab sis koj yuav tsum tau paub qhov tshwj xeeb ionic nqi elments.
Dab tsi yog ion thiab piv txwv?
Ib ion yog ib tug atom los yog ib pawg ntawm atoms uas cov xov tooj ntawm electrons txawv ntawm cov xov tooj ntawm protons. Yog hais tias tus xov tooj ntawm electrons tsawg tshaj li tus xov tooj ntawm protons qhov kev siv yog ib tug zoo. ion , kuj hu ua cation. Ex: sodium ion Na+, chloride ion cl-, thiab oxide ion O2 -

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
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
Dab tsi yog ionic nqi ntawm tooj liab?
Copper (I) ions muaj 1+ nqi. Nws cov qauv yog Cu +. Copper (II) ions muaj 2+ nqi. Qhov no tshwm sim thaum tooj liab atoms poob ob electrons
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
