Atomic radius yog txiav txim raws li qhov kev ncua deb ntawm lub nuclei ntawm ob zoo tib yam atoms koom ua ke. Cov atomic radius ntawm atoms feem ntau txo qis ntawm sab laug mus rau sab xis hla ib lub sijhawm. Cov atomic radius ntawm atoms feem ntau nce saum toj mus rau hauv qab hauv ib pab pawg.

Tsuas yog li ntawd, koj yuav ua li cas kwv yees atomic radius?

Periodic Trends ntawm Atomic Radius

  1. Ib qho atom tau loj dua li cov khoom siv hluav taws xob ntau ntxiv; Yog li ntawd lub vojvoog ntawm atoms nce thaum koj nqis mus rau ib pab pawg hauv lub sijhawm ntawm cov ntsiab lus.
  2. Feem ntau, qhov loj ntawm lub atom yuav txo qis thaum koj txav ntawm sab laug mus rau sab xis ntawm ib lub sijhawm.

Ib sab saum toj no, vim li cas atomic radius tseem ceeb? Qhov loj ntawm atoms yog tseem ceeb thaum sim piav qhia tus cwj pwm ntawm atoms los yog compounds. Ib txoj hauv kev uas peb tuaj yeem nthuav qhia qhov loj ntawm atoms yog nrog cov atomic radius . Cov ntaub ntawv no pab peb nkag siab tias vim li cas qee cov molecules haum ua ke thiab yog vim li cas lwm cov molecules muaj qhov chaw uas muaj neeg coob heev nyob rau hauv tej yam kev mob.

Qhov thib ob, qhov twg yog qhov atomic radius ntawm lub rooj zaum?

Kev piav qhia: Electron affinity feem ntau nce ntawm sab laug mus rau sab xis thiab hauv qab mus rau saum. Kev piav qhia: Lub caij nyoog trends qhia tias atomic radius nce ib pab pawg thiab los ntawm sab laug mus rau sab xis hla ib lub sijhawm. Yog li ntawd, oxygen muaj ib qho me me atomic radius sulfur.

Dab tsi yog atomic radius thiab nws ntsuas li cas?

Cov atomic radius yog a ntsuas ntawm qhov loj ntawm ib atom . Cov atomic radius txhais tau tias yog ib nrab ntawm qhov kev ncua deb ntawm lub nuclei ntawm ob qho tib si atoms uas yog sib koom ua ke. Atomic radius yog nyob ntawm hom daim ntawv cog lus tam sim no.
