Atomic radii tau ntsuas rau cov ntsiab lus. Cov units rau atomic radii yog picometers , sib 10−12 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
- Luas = 1 x 10-12 ' meter ' (meter)
- 100 pm = 1 Ångstrom.
- 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.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?
Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360
Koj pom atomic radius li cas?
Atomic radius yog txiav txim siab raws li qhov kev ncua deb ntawm lub nuclei ntawm ob qho tib si atoms sib koom ua ke. Lub atomic radius ntawm atoms feem ntau txo qis ntawm sab laug mus rau sab xis hla ib lub sijhawm. Lub atomic radius ntawm atoms feem ntau nce los ntawm sab saum toj mus rau hauv qab nyob rau hauv ib pawg
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
Yuav ua li cas koj pom lub tangent ntawm lub kaum sab xis ntawm lub voj voog?
Lub voj voog chav tsev muaj ntau qhov sib txawv uas txhua tus muaj qhov sib thooj ntawm lub voj voog. Thecoordinates ntawm txhua lub ntsiab lus muab peb txoj hauv kev los nrhiav qhov tangent ntawm txhua lub kaum ntse ntse. Lub tangent ntawm lub kaum sab xis yog sib npaug rau y-coordinate muab faib los ntawm x-coordinate
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
