Txhua plhaub tuaj yeem muaj tus lej tas li ntawm electrons : Thawj plhaub tuaj yeem tuav tau ob electrons , ob plhaub tuaj yeem tuav txog yim (2 + 6) electrons , peb plhaub tuaj yeem tuav txog 18 (2 + 6 + 10) thiab lwm yam. General formula yog qhov nth plhaub tuaj yeem nyob hauv txoj cai tuav txog 2(n2) electrons.
Kuj paub yog, dab tsi yog lub plhaub hauv electron configuration?
Ib electron plhaub yog sab nraud ntawm ib qho atom nyob ib ncig ntawm lub atomic nucleus. Nws yog qhov chaw hluav taws xob s yog, thiab yog ib pawg ntawm atomic orbitals nrog tib tus nqi ntawm tus thawj tswj hwm quantum tooj n.
pes tsawg electrons nyob rau hauv txhua lub plhaub? Txhua lub plhaub tuaj yeem muaj tus lej tas li ntawm electrons : Thawj plhaub tuaj yeem tuav tau ob electrons , ob plhaub tuaj yeem tuav txog yim (2 + 6) electrons , peb plhaub tuaj yeem tuav txog 18 (2 + 6 + 10) thiab lwm yam. General formula yog qhov nth plhaub tuaj yeem nyob hauv txoj cai tuav txog 2(n2) electrons.
Qhov thib ob, koj tuaj yeem qhia tau pes tsawg lub valence electrons ib lub caij muaj?
Rau nruab nrab atoms, tus naj npawb ntawm valence electrons yog sib npaug rau atom lub ntsiab pab pawg naj npawb. Lub ntsiab pab pawg naj npawb rau ib keeb tuaj yeem pom los ntawm nws kab ntawv ntawm lub sijhawm teem sijhawm. Piv txwv li, carbon yog nyob rau hauv pawg 4 thiab muaj 4 valence electrons . Oxygen yog nyob rau hauv pawg 6 thiab muaj 6 valence electrons.
Vim li cas tsuas muaj 8 electrons nyob rau hauv lub plhaub sab nrauv?
Lub yim- electrons stability ntawm lub atom yog stemmed los ntawm stability ntawm noble gases los yog cov laus lub npe inert gases, uas tau ntev tau paub tias yog unreactive los yog noble. Txawm li cas los xij, txoj cai no yog tsim nyog rau cov ntsiab lus ntawm kab thib ob hauv lub rooj zaum, uas lawv sab nraud - plhaub muaj peev xwm yog 8 electron.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?
Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360
Lub caij twg muaj pes tsawg tus electron plhaub li calcium?
Yog lawm, calcium txhais tau tias yog hlau vim nws lub cev thiab tshuaj lom neeg. Lawv txhua tus muaj lub plhaub sab nraud nrog ob lub tshuab hluav taws xob thiab muaj zog heev. Cov ntsiab lus hauv kab thib ob muaj ob lub tshuab hluav taws xob npaj ua cov sib txuas. Nws yuav tsum tsis txhob surprise koj tias calcium muaj valence ntawm 2
Yuav ua li cas koj pom lub tangent ntawm lub kaum sab xis ntawm lub voj voog?
Lub voj voog chav tsev muaj ntau qhov sib txawv uas txhua tus muaj qhov sib thooj ntawm lub voj voog. Thecoordinates ntawm txhua lub ntsiab lus muab peb txoj hauv kev los nrhiav qhov tangent ntawm txhua lub kaum ntse ntse. Lub tangent ntawm lub kaum sab xis yog sib npaug rau y-coordinate muab faib los ntawm x-coordinate
Yuav ua li cas koj pom cov ions ntawm ib lub caij?
Tshem tawm cov hluav taws xob los ntawm Protons Tshem tawm cov xov tooj ntawm cov hluav taws xob los ntawm cov xov tooj ntawm protons hauv ib lub atom raws li ib txoj hauv kev los xam cov nqi ntawm theion. Piv txwv li, yog hais tias ib tug sodium atom poob ib tug electron, workout 11 - 10 = 1. Ib tug sodium ion muaj ib tug +1 nqi, sau tseg asNa +
Yuav ua li cas koj pom thawj lub caij nplooj zeeg hauv lub caij nplooj zeeg dawb?
VIDEO Dhau li ntawm no, koj yuav nrhiav sijhawm li cas hauv lub caij nplooj zeeg dawb? Dawb lub caij nplooj zeeg / poob nrawm sib npaug Lub ntiajteb txawj nqus, g = 9.8 m/s 2 Lub ntiajteb txawj nqus ceev koj ntawm 9.8 meters ib ob ib ob.
