4 block

Ib yam li ntawd, 4 blocks ntawm lub rooj zaum yog dab tsi?

Teb thiab piav qhia: Lub daim ntawv qhia hnub muab faib ua plaub blocks uas hu ua s, p, d, thiab f.

Qhov thib ob, 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.

Hauv qhov no, dab tsi yog qhov thaiv ntawm lub rooj zaum?

A thaiv ntawm daim ntawv qhia hnub yog ib txheej 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.

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.
