Atomic radii tau ntsuas rau cov ntsiab lus. Cov units rau atomic radii yog picometers , sib 1012 meters. Raws li kev piv txwv, qhov kev ncua deb ntawm ob lub hydrogen atoms hauv H2 molecule ntsuas yog 74 pm . Yog li ntawd, lub atomic radius ntawm ib hydrogen atom ua 742:37 pm 74 2 = 37 pm.

Ntawm no, koj ua li cas xam cov atomic radius ntawm carbon?

nyob deb O2 luv vim yog ob daim ntawv cog lus txuas rau ob atoms . Daim ntawv cog lus ntev hauv CC yog: 142.6 (graphite) pm. Muaj ntau ntau txoj hauv kev los txhais lub vojvoog rau atoms thiab ions.

Carbon: radii ntawm atoms thiab ions

  1. Luas = 1 x 10-12 ' meter ' (meter)
  2. 100 pm = 1 Ångstrom.
  3. 1000pm = 1 nanometer (nm, nanometer)

Koj ntsuas atomic radius li cas? Kev ntsuas ntawm atomic radius Cov lub vojvoog ntawm ib atom tuaj yeem pom los ntawm ntsuas qhov kev ncua deb ntawm lub nuclei ntawm ob kov atoms , thiab tom qab ntawd halving qhov kev ncua deb. Raws li koj tuaj yeem pom los ntawm cov duab kos, tib yam atom tuaj yeem pom muaj qhov sib txawv lub vojvoog nyob ntawm seb nyob ib ncig ntawm nws.

Nyob rau hauv no txoj kev, lub atomic radius nyob qhov twg?

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 sib txawv 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 units rau atomic radius?

Chav nyob siv los ntsuas atomic radius: Angstroms ( Å ): Qhov no yog chav tsev feem ntau siv. 1.0 x 10-10 meters. Nanometer (nm): Sib npaug rau 1.0 x 10-9 meters.
