Ionic compounds feem ntau daim ntawv nruab nrab cov ntsiab lus uas yog hlau thiab cov ntsiab lus uas yog nonmetals. Piv txwv li, hlau calcium (Ca) thiab nonmetal chlorine (Cl) daim ntawv tus ionic compound calcium chloride (CaCl2). Hauv no compound , muaj ob yam tsis zoo chloride ions rau txhua qhov zoo calcium ion.
Ib yam li ntawd, tib neeg nug, dab tsi yog cov ntsiab lus ionic?
Ionic compounds yog cov khoom sib xyaw ua ke ions . Ob- keeb cov tshuaj feem ntau yog ionic thaum ib keeb yog hlau thiab lwm yam yog tsis-hlau. Piv txwv li: sodium chloride: NaCl, nrog Na+ thiab Cl- ions . calcium phosphide: Ca3P2, nrog Ca2+ thiab P3- ions.
Ib co piv txwv ntawm ionic bonds yog dab tsi? Ionic daim ntawv cog lus piv txwv muaj xws li:
- LiF - Lithium Fluoride.
- LiCl - Lithium Chloride.
- LiBr - Lithium Bromide.
- Li-Iodide Lithium Iodide.
- NaF - Sodium Fluoride.
- NaCl - Sodium Chloride.
- NaBr - Sodium Bromide.
- NaI - Sodium Iodide.
Tsuas yog li ntawd, dab tsi ua rau ib qho ionic compound?
Ionic compounds yog tshuaj sib xyaw ua los ntawm ions . Cov no ions yog atoms uas nce lossis poob electrons, muab lawv tus nqi zoo lossis tsis zoo. Cov hlau zoo li plam electrons, yog li lawv dhau los ua cations thiab muaj cov txiaj ntsig zoo. Nonmetals zoo li tau txais electrons, tsim cov anions uas muaj tus nqi tsis zoo.
Yuav ua li cas koj txheeb xyuas daim ntawv cog lus ionic?
Muaj ob peb txoj kev sib txawv txiav txim yog tias a daim ntawv cog lus yog ionic los yog covalent. Los ntawm txhais, ib ionic daim ntawv cog lus yog nruab nrab ntawm ib tug hlau thiab ib tug nonmetal, thiab ib tug covalent daim ntawv cog lus yog nruab nrab ntawm 2 nonmetals. Yog li koj feem ntau tsuas yog saib ntawm lub rooj zaum thiab txiav txim seb koj cov khoom puas yog ua los ntawm cov hlau / nonmetal lossis tsuas yog 2 nonmetals.

Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Cov nqe lus twg piav qhia vim li cas lub ntsiab lus carbon tsim muaj ntau lub tebchaw?
Cov pa roj carbon monoxide yog tib lub ntsiab lus uas tuaj yeem tsim muaj ntau lub tebchaw sib txawv vim tias txhua cov pa roj carbon atom tuaj yeem tsim plaub daim ntawv cog lus tshuaj rau lwm cov atoms, thiab vim tias cov pa roj carbon atom tsuas yog txoj cai, me me kom haum rau hauv qhov chaw ntawm cov molecules loj heev
Cov ntsiab lus twg tsis khi rau tsim cov molecules?
Ib lub molecule yog ib pawg nruab nrab ntawm cov atoms uas tau koom ua ke los ntawm ib los yog ntau dua covalent bonds. Qhov twg ntawm cov ntsiab lus no tsis sib koom ua cov molecules: oxygen, chlorine, neon, lossis sulfur? neon vim hais tias nws yog ib tug noble roj thiab tsis xav qhia electrons nrog rau lwm cov atoms
