Hluav taws xob, lightest ruaj khov subatomic particle paub. Nws nqa tus nqi tsis zoo ntawm 1.602176634 × 10−19 coulomb, uas yog suav hais tias yog lub hauv paus ntawm cov nqi hluav taws xob. Tus so loj ntawm lub electron yog 9.1093837015 × 10−31 kg, uas tsuas yog 1/1, 836qhov loj ntawm ib tug proton.
Tom qab ntawd, dab tsi yog 3 hom subatomic hais?
Protons , neutrons , thiab electrons yog peb lub ntsiab subatomic hais pom nyob rau hauv ib lub atom. Protons muaj tus nqi zoo (+). Ib qho yooj yim kom nco ntsoov qhov no yog kom nco ntsoov tias ob qho tib si proton thiab zoo pib nrog tsab ntawv "P." Neutrons tsis muaj hluav taws xob.
Qhov thib ob, dab tsi yog qhov subatomic hais thiab lawv cov khoom? Subatomic hais muaj xws li electrons , tus nqi tsis zoo, yuav luag tsis muaj qhov loj me uas txawm li cas los xij rau feem ntau ntawm qhov loj ntawm lub atom, thiab lawv suav nrog lub tsev hnyav dua ntawm cov me me tab sis ntom ntom ntawm lub atom, qhov zoo them. protons thiab hluav taws xob nruab nrab neutrons.
Kuj Paub, vim li cas electron yog ib qho khoom ruaj khov?
Cov hluav taws xob , ntawm qhov tod tes, yog xav tau ruaj khov ntawm theoretical grounds: lub hluav taws xob yog qhov tsawg kawg nkaus particle nrog tsis yog xoom hluav taws xob, yog li nws txoj kev lwj yuav ua txhaum kev txuag nqi.
Dab tsi yog qhov subatomic particle ntawm proton?
Proton. Proton, ruaj khov subatomic particle uas muaj qhov zoo nqi sib npaug hauv qhov loj rau ib chav tsev ntawm electron nqi thiab qhov hnyav ntawm 1.67262 × 10−27 kg, uas yog 1,836 lub sij hawm qhov loj ntawm ib tug electron.

Dab tsi yog qhov hnyav tshaj plaws uas muaj tsawg kawg yog ib qho isotope ruaj khov?
Bismuth-209 (209Bi) yog lub isotope ntawm bismuth nrog ntev tshaj plaws paub ib nrab-lub neej ntawm ib tug radioisotope uas undergoes α-decay (alpha decay). Nws muaj 83 protons thiab cov khawv koob ntawm 126 neutrons, thiab atomic mass ntawm 208.9803987 amu (atomic mass units). Bismuth-209. General Protons 83 Neutrons 126 Nuclide data Ntuj abundance 100%
Qhov piv txwv ruaj khov equilibrium yog dab tsi?
Ib phau ntawv dag ntawm kab rov tav yog ib qho piv txwv ntawm qhov sib npaug ruaj khov. Yog tias phau ntawv raug tshem tawm ntawm ib ntug thiab tom qab ntawd tso cai rau poob, nws yuav rov qab los rau qhov qub. Lwm cov piv txwv ntawm kev ruaj khov yog lub cev pw hauv pem teb xws li lub rooj zaum, rooj zaum thiab lwm yam
Dab tsi yog qhov chaw ruaj khov hauv Bohr tus qauv atomic?
Ib lub atom muaj ntau lub voj voog ruaj khov uas lub tshuab hluav taws xob tuaj yeem nyob tsis muaj emission ntawm lub zog hluav taws xob. Txhua lub orbit sib raug, mus rau ib theem zog. 4. Ib qho chaw tshwj xeeb nyob ib ncig ntawm lub nucleus uas muaj cov kab sib npaug ntawm lub zog thiab lub vojvoog hu ua lub plhaub
Dab tsi yog qhov chaw nyob ruaj khov nyob rau hauv nyias txheej chromatography?
Lub silica gel (los yog alumina) yog qhov chaw nres tsheb. Cov theem nyob ruaj khov rau nyias txheej txheej chromatography kuj feem ntau muaj cov khoom siv fluorescesin UV teeb - vim li cas koj yuav pom tom qab. Lub mobilephase yog cov kuab tshuaj uas tsim nyog los yog sib tov ntawm cov kuab tshuaj
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
