Rutherford tus qauv ntawm atom (ESAAQ)
Rutherford tau ua qee qhov kev sim uas ua rau muaj kev hloov pauv ntawm cov tswv yim nyob ib puag ncig atom . Nws tus tshiab qauv piav txog atom Raws li ib tug me me, ntom, zoo them core hu ua ib tug nucleus surrounded los ntawm sib dua, tsis zoo them electrons.
Tom qab ntawd, dab tsi yog tus qauv ntxov tshaj plaws ntawm lub atom?
Thomson, uas nrhiav tau lub tshuab hluav taws xob hauv xyoo 1897, tau tshaj tawm cov paj npleg plum qauv ntawm lub atom nyob rau hauv 1904 ua ntej lub discovery ntawm lub atomic nucleus thiaj li muaj cov electron nyob rau hauv lub atomic qauv . Hauv Thomson's qauv , cov atom yog tsim los ntawm electrons (uas Thomson tseem hu ua "corpuscles," txawm tias G. J.
leej twg tsim thawj atomic qauv? Democritus
Tom qab, lo lus nug yog, dab tsi yog 5 atomic qauv?
- Dalton qauv (Billiard pob qauv)
- Thomson qauv (Plum pudding qauv)
- Lewis qauv (Cubical atom qauv)
- Nagaoka qauv (Saturnian qauv)
- Rutherford qauv (Planetary qauv)
- Bohr qauv (Rutherford-Bohr qauv)
- Bohr-Sommerfeld qauv (Refined Bohr qauv)
- Gryziński qauv (dawb-lub caij nplooj zeeg qauv)
Tus qauv atom yog dab tsi?
Ib atom yog qhov tsawg tshaj plaws ntawm txhua lub caij uas tseem khaws cov yam ntxwv ntawm lub caij ntawd. Niels Bohr yog ib tug kws tshawb fawb Danish uas tau qhia txog qauv ntawm ib atom xyoo 1913. Bohr's qauv muaj lub hauv paus nucleus ncig los ntawm cov khoom me me hu ua electrons uas yog orbiting lub nucleus hauv huab.

Neil Bohr atomic qauv yog dab tsi?
Niels Bohr tau npaj Bohr Model ntawm Atom hauv xyoo 1915. Bohr Model yog ib qho qauv ntawm lub ntiaj teb uas cov electrons tsis zoo orbit ib tug me me, zoo nqi nucleus zoo ib yam li cov ntiaj chaw orbiting lub hnub (tshwj tsis yog lub orbits tsis yog planar)
Dab tsi yog oxygen atomic qauv?
Daim duab qhia txog qhov muaj pes tsawg leeg ntawm nuclear thiab hluav taws xob teeb tsa ntawm ib qho atom ntawm oxygen-16 (atomic naj npawb: 8), feem ntau isotope ntawm lub caij oxygen. Lub nucleus muaj 8 protons (liab) thiab 8 neutrons (xiav). Qhov kev ruaj ntseg ntawm cov khoom siv hluav taws xob sab nraud txiav txim siab nws cov khoom siv tshuaj thiab lub cev
Tus qauv txiav txim thawj zaug hauv kev txheeb cais yog dab tsi?
0.1.1 Thawj-Order-Model. Lub sij hawm ua ntej qhia tias cov kev hloov pauv ywj pheej tsuas yog suav nrog thawj lub zog, peb tom qab pom tias peb tuaj yeem nce qhov kev txiav txim. Tus Qauv Ua Ntej-Order hauv Quantitative Variables. y = β0 + β1x1 + β2x2 + + βkxk + e
Dab tsi yog atomic packing factor ntawm cov qauv siv lead ua?
Atomic packing factor tseem hu ua packing efficiency ntawm crystal. Nws txhais tau tias yog qhov ntim tau los ntawm kev sib txuas tag nrho cov atoms ntawm ib lub cell hauv kev sib piv rau tag nrho cov ntim ntawm ib chav tsev cell, piv txwv li nws yog ib feem ntawm lub ntim nyob los ntawm tag nrho cov atoms nyob rau hauv ib chav tsev cell mus rau tag nrho cov ntim ntawm ib chav tsev cell
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
