A thaiv ntawm daim ntawv qhia hnub yog ib pawg ntawm cov khoom siv tshuaj muaj lawv qhov sib txawv ntawm cov electrons feem ntau hauv tib hom atomic orbital. Txhua thaiv muaj npe tom qab nws cov yam ntxwv orbital: s- thaiv ,p- thaiv ,d- thaiv , thiab f- thaiv.
Ib yam li ntawd, dab tsi yog 4 blocks ntawm lub rooj zaum?
Teb thiab piav qhia: Lub daim ntawv qhia hnub muab faib ua plaub blocks uas hu ua s, p, d, thiab f.
Tsis tas li ntawd, yog vim li cas lub sij hawm lub sij hawm faib ua blocks? Raws li electron configurations, lub daim ntawv qhia hnub tuaj yeem yog muab faib ua blocks denoting uas sublevel yog nyob rau hauv tus txheej txheem ntawm kev sau. s, p, d, thiab f thaiv tau piav qhia hauv qab no. Daim duab kuj qhia txog yuav ua li cas lub d sublevel yog ib qho tseem ceeb theem tom qab lub sij hawm nyob rau hauv uas sublevel tshwm sim.
Dab tsi yog peb qhov tshwj xeeb blocks nyob rau hauv lub sij hawm?
Element blocks muaj npe rau lawv cov yam ntxwv orbital, uas yog txiav txim los ntawm lub zog siab tshaj plaws electrons:
- s-block. Thawj ob pawg ntawm lub rooj sib tham, s-block hlau:
- p-block. P-thaiv cov ntsiab lus suav nrog rau lub xeem rau pawg ntawm lub rooj zaum, tsis suav nrog helium.
- d-block.
- f-block.
Vim li cas thiaj hu ua S block?
Cov s - thaiv cov khoom sib koom electron configuration. s - thaiv cov ntsiab lus yog cov ntsiab lus pom nyob rau hauv Pawg 1 thiab Pab Pawg 2 ntawm lub rooj sib tham. Vim tias lawv muaj 2 valence electrons lawv tsis tshua muaj zog dua li pawg 1. Hydrogen yog ib pawg nonmetal nrog cov alkali hlau vim nws muaj ib qho hluav taws xob hauv nws lub plhaub valence.
Pom zoo:
Dab tsi yog lub ntsiab lus 11 ntawm lub rooj zaum?
Sodium yog lub ntsiab lus uas yog atomic naj npawb 11 ntawm lub sijhawm teem sijhawm
Dab tsi yog thawj lub ntsiab lus ntawm lub rooj zaum?
Hydrogen yog thawj lub hauv paus ntawm lub rooj sib tham, nrog qhov nruab nrab atomic loj ntawm 1.00794
Dab tsi yog lub ntsiab lus thib peb ntawm lub rooj zaum?
Lithium yog qhov thib 3 ntawm lub caij nyoog ntawm cov ntsiab lus
Dab tsi yog ib qho atom ntawm lub rooj zaum?
Ib qho atom yog qhov tsawg tshaj plaws ntawm cov teeb meem zoo tib yam uas tsim cov tshuaj lom neeg. Txhua yam khoom, kua, roj, thiab plasma yog tsim los ntawm atoms. Txhua lub atom yog tsim los ntawm ib tug nucleus thiab ib los yog ntau dua electrons khi rau lub nucleus. Lub nucleus yog tsim los ntawm ib los yog ntau tshaj protons thiab ib tug xov tooj ntawm neutrons
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
