Teb: Aluminium yog nyob rau hauv pawg IIIA ntawm lub sij hawm lub sij hawm yog li ntawd nws muaj peb valence electrons . Cov cim rau aluminium yog Al uas yuav nyob ib puag ncig peb dots . 2.
Kuj paub, dab tsi yog lub cim electron dot?
Electron Dot Structures - cov cuab yeej pab tau rau kev xav txog kev sib txuas lus. Electron dot qauv - valence electrons yog sawv cev los ntawm dots muab tso rau ib ncig ntawm cov tshuaj cim . Hluav taws xob muab tso rau ob sab ntawm txhua sab ntawm lub elemental cim rau qhov siab tshaj plaws ntawm yim, uas yog tus naj npawb ntawm electrons nyob rau hauv ib lub plhaub puv s thiab p.
Qhov thib ob, daim duab kos duab electron rau nitrogen yog dab tsi? Electron Dot Daim duab
| lithium | 1 s ib 2 2 s ib 1 | 1 valence electron |
|---|---|---|
| beryllium | 1 s ib 2 2 s ib 2 | 2 valence electrons |
| nitrogen | 1 s ib 2 2 s ib 2 2 ib p 3 | 5 valence electrons |
| neon | 1 s ib 2 2 s ib 2 2 ib p 6 | 8 valence electrons |
Tsis tas li lo lus nug yog, pes tsawg tus electrons sawv cev hauv Lewis dot qauv rau txhuas AL?
Qhov ntawd txhais tau tias muaj 13 electrons nyob rau hauv aluminium atom. Saib ntawm daim duab, koj tuaj yeem pom muaj ob lub electrons hauv plhaub ib, yim hauv plhaub ob, thiab peb hauv plhaub peb.
Dab tsi yog qhov txawv ntawm cation thiab anion?
Anion vs. Cation . Ions tshwm sim los ntawm atoms los yog molecules uas tau txais los yog poob ib los yog ntau tshaj valence electrons, muab lawv ib tug zoo los yog tsis zoo nqi. Cov nrog a tus nqi tsis zoo hu ua anions thiab cov nrog a tus nqi zoo raug hu cations.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov twg yog qhov tseeb dua qhov hloov pauv pipette lossis ntsuas pipette?
Kawm tiav pipettes yog tsawg dua li volumetric pipettes. Mohr kawm tiav pipettes, uas yog qee zaum hu ua "drain out pipettes", tau cim nrog xoom thaum pib ntawm lawv qhov kawg conical, thaum Serological kawm tiav pipettes, tseem hu ua "tsov tawm pipettes", tsis txhob tso cov cim xoom
Vim li cas qhov tseeb thiab qhov tseeb yog qhov tseem ceeb hauv kev tshawb fawb?
Qhov tseeb sawv cev rau qhov kev ntsuas ze npaum li cas los ntawm nws qhov tseeb. Qhov no yog qhov tseem ceeb vim tias cov cuab yeej tsis zoo, cov ntaub ntawv ua haujlwm tsis zoo lossis tib neeg yuam kev tuaj yeem ua rau cov txiaj ntsig tsis raug uas tsis ze rau qhov tseeb. Precision yog qhov ze npaum li cas ntawm cov kev ntsuas ntawm tib yam yog rau ib leeg
Kuv yuav ua li cas thiaj paub tseeb tias kuv qhov ntsuas digital yog qhov tseeb?
Ntsuas ob yam khoom ua ke. Muab ib qho khoom tso rau ntawm qhov ntsuas. Nco ntsoov qhov hnyav. Tshem nws tawm thiab cia lub nplai txawm rov qab tawm. Yog tias nws phim, qhov ntsuas yog qhov tseeb. Yog tias nws tsis yog, sim dua thiab saib seb nws puas tawm los ntawm tib tus lej. Yog tias nws yog, nws yuav yog tias koj qhov ntsuas ib txwm tawm ntawm tus nqi ntawd
Lub electron dot daim duab rau Helium yog dab tsi?
Yog li ntawd Helium tsuas muaj 2 valence electrons. Nws tau muab tso rau hauv Pawg 8A vim tias nws lub plhaub sab nraud yog tag nrho nrog ob lub tshuab hluav taws xob. Thaum koj kos tus qauv Lewis rau Helium koj yuav muab ob lub 'dots' lossis valance electrons nyob ib ncig ntawm lub cim cim (Nws)
