Cov atomic radius ntawm ib qho tshuaj keeb yog qhov kev ncua deb ntawm qhov nruab nrab ntawm lub nucleus mus rau lub plhaub sab nraud ntawm electron.
Ib yam li ntawd, tib neeg nug, qhov twg yog qhov atomic radius ntawm lub rooj zaum?
Table ntawm Atomic Radii
| Atomic Number | Element Symbol | Atomic Radius [Å] |
|---|---|---|
| 10 | Ne | 0.38 |
| 11 | Na | 1.90 |
| 12 | Mg | 1.45 |
| 13 | Al | 1.18 |
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov atomic radius ntawm manganese? Atomic Radius ntawm cov khoom
| Helium | 31pm ua | 161pm ua |
|---|---|---|
| Hlau | 156pm ua | 231pm ua |
| Is Nrias teb | 156pm ua | 233pm ua |
| Thallium | 156pm ua | 238pm ua |
| Manganese | 161pm ua | 243pm ua |
Ntawm no, lub vojvoog ntawm ib lub ntsiab yog dab tsi?
Lub atomic lub vojvoog (r) ntawm ib qho atom tuaj yeem txhais tau tias yog ib nrab ntawm qhov kev ncua deb (d) nruab nrab ntawm ob lub nuclei hauv diatomic molecule. Atomic radii tau ntsuas rau cov ntsiab lus. Cov units rau atomic radii yog picometers, sib npaug rau 10−12 meters.
Dab tsi yog atomic radius siv rau?
Lo lus no piav txog qhov loj ntawm ib qho Atom -Tab sis nws tsis yog qhov tseeb D. Atomic radius yog ib lo lus siv rau piav qhov loj ntawm ib atom . Txawm li cas los xij, tsis muaj tus qauv txhais rau tus nqi no. Cov atomic radius tuaj yeem xa mus rau ionic lub vojvoog , covalent lub vojvoog , hlau lub vojvoog los yog van der Waals lub vojvoog.
