High melting thiab boiling ntsiab lus - Ionic daim ntawv cog lus muaj zog heev - xav tau ntau lub zog los rhuav tshem lawv. Yog li ionic compounds muaj siab melting thiab boiling ntsiab lus. Conductive thaum ua kua - Ions raug nqi hais, tab sis ionic compounds tsuas tuaj yeem ua hluav taws xob yog tias lawv cov ions dawb txav mus.
Tsuas yog li ntawd, daim ntawv cog lus twg muaj qhov siab tshaj plaws melting point?
1 Teb. Ernest Z. Cov lus teb luv luv: Cov ntsiab lus nrog ionic bonding muaj cov ntsiab lus melting ntau dua dua cov nrog covalent kev sib raug zoo . Intermolecular rog txiav txim siab melting cov ntsiab lus ntawm cov tebchaw.
Tsis tas li, cov tshuaj twg muaj cov ntsiab lus melting siab? Feem ntau, ionic compounds muaj cov ntsiab lus melting siab vim tias cov hluav taws xob hluav taws xob txuas cov ions - kev sib cuam tshuam ion-ion - muaj zog. Nyob rau hauv cov organic tebchaw, muaj polarity, tshwj xeeb tshaj yog hydrogen bonding, feem ntau ua rau lub melting point ntau dua.
Ua raws li qhov no hauv kev txiav txim siab, vim li cas ionic daim ntawv cog lus muaj qhov siab melting point?
Ionic compounds muaj cov ntsiab lus melting siab vim muaj yog a muaj zog electrostatic quab yuam ntawm attraction ntawm oppositely them ions thiab yog li ntawd yuav tsum muaj ntau lub zog los rhuav tshem lub zog kev sib raug zoo zog nruab nrab 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.

Cov nanotubes puas muaj cov ntsiab lus melting siab?
Qhov teeb tsa tau tso cai tswj hwm tus kheej nanoparticles thiab cua sov tus neeg CNTs los ntawm kev siv tam sim no rau lawv. CNTs tau pom los tiv thaiv qhov kub thiab txias, mus txog qhov melting point ntawm 60-nm-inch W particles (~ 3400 K)
Cov hlau hloov pauv puas muaj cov ntsiab lus melting tsawg?
Cov ntsiab lus melting-cov ntsiab lus ntawm cov hlau hloov pauv yog siab vim 3d electrons muaj rau cov hlau sib txuas. Qhov ntom ntawm cov hlau hloov pauv yog siab rau tib yam li cov ntsiab lus kub kub. Cov hlau hloov pauv yog tag nrho cov hlau ntom ntom nrog cov ntsiab lus siab melting thiab kub kub
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
