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
- 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.
- 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.

Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Yuav ua li cas koj pom lub atomic radius ntawm PM?
Atomic radii tau ntsuas rau cov ntsiab lus. Cov units rau atomic radii yog picometers, sib npaug rau 10− 12 meters. Ua piv txwv, qhov kev ncua deb ntawm ob lub hydrogen atoms hauv H2 molecule yog ntsuas los ntawm 74 teev tsaus ntuj. Yog li ntawd, lub atomic radius ntawm ib tug hydrogen atom yog 742 = 37 pm 74 2 = 37 pm
Yuav ua li cas coulombic attraction cuam tshuam rau atomic radius?
Raws li Coulomb txoj cai lij choj, raws li tus naj npawb atomic nce nyob rau hauv ib tug series ntawm atoms, lub nuclear attraction rau electrons kuj yuav nce, yog li rub lub electron kom ze rau lub nucleus. Xws li kev sib raug zoo ntawm tus lej atomic thiab atomic radius yog qhov sib txuas ncaj qha
Atomic radius nce li cas?
Qhov no yog tshwm sim los ntawm qhov nce ntawm cov protons thiab electrons nyob rau ib lub sij hawm. Ib qho proton muaj txiaj ntsig ntau dua li ib qho hluav taws xob; Yog li, electrons raug rub mus rau lub nucleus, ua rau lub vojvoog me me. Atomic radius nce saum toj mus rau hauv qab hauv ib pab pawg. Qhov no yog tshwm sim los ntawm electron shielding
Yog vim li cas lub sij hawm lub sij hawm teem los ntawm atomic tooj thiab tsis atomic mass?
Vim li cas lub Sijhawm Table yog teem los ntawm tus lej atomic thiab tsis yog atomic mass? Atomic tooj yog tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm txhua lub ntsiab lub atoms. Tus lej ntawd tshwj xeeb rau txhua yam. Atomic loj yog txiav txim los ntawm tus naj npawb ntawm protons thiab neutrons ua ke
