Subatomic hais suav nrog electrons, qhov tsis zoo them, yuav luag tsis muaj zog cov khoom Txawm li cas los xij, suav nrog 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, cov khoom siv hluav taws xob zoo thiab cov hluav taws xob tsis zoo neutrons.
Hais txog qhov no, dab tsi yog subatomic hais piav txog txhua?
Cov khoom uas me dua lub atom hu ua subatomic particles. Peb lub ntsiab subatomic hais uas tsim ib lub atom yog protons , neutrons , thiab electrons . Qhov chaw ntawm lub atom hu ua lub nucleus. Ua ntej, cia peb kawm me ntsis txog protons thiab neutrons , thiab tom qab ntawd peb yuav tham txog electrons me ntsis tom qab.
Muaj pes tsawg hom subatomic hais? Muaj ob hom ntawm subatomic hais: elementary thiab composite hais. Muaj 36 qhov paub tseeb tias qhov tseem ceeb, suav nrog cov khoom tiv thaiv, raws li xibfwb Craig Savage los ntawm Australian National University.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog antiquark?
Cov duab yooj yim heev ntawm cov protons, neutrons, pions, thiab lwm yam hadrons qhia tias lawv yog ua los ntawm quarks (daj spheres) thiab antiquarks (ntsuab spheres), uas yog khi ua ke los ntawm gluons (bent ribbons). Combinations ntawm cov quarks u, d, thiab s thiab lawv sib xws antiquarks los tsim hadrons.
Subatomic particles tsim li cas?
Thaum lub sij hawm no tawg thawj subatomic hais uas ua rau muaj teeb meem thiab lub zog tsim . Thaum 10^-11 vib nas this lub zog tsis muaj zog nuclear sib cais rau lwm tus, tso cai tsim cov thawj quarks, lub tsev thaiv ntawm subatomic hais . Tom qab ntawd, ntawm 10^-4 vib nas this thawj protons thiab neutrons tau tsim.

Yuav ua li cas cov tsev neeg ntawm kev ua haujlwm tsis thiab cov lus piav qhia ntawm cov duab cuam tshuam?
Cov tsev neeg muaj nuj nqi yog pab pawg ua haujlwm nrog qhov zoo sib xws uas ua rau lawv yooj yim rau kev teeb tsa thaum koj paub txog kev ua haujlwm ntawm niam txiv, qhov piv txwv yooj yim tshaj plaws ntawm daim ntawv. Ib qho parameter yog qhov sib txawv hauv cov kab zauv dav dav uas siv rau ntawm tus nqi tshwj xeeb txhawm rau tsim ib qho kev sib npaug
Cov nqe lus twg zoo tshaj plaws piav qhia txog qhov tseem ceeb ntawm cov lus qhia muaj nuj nqis?
Qhov tsis suav nrog tus nqi ntawm ib qho kev qhia rational yog qhov tseem ceeb uas tus denominator ntawm qhov kev qhia yog xoom. Tsis tas li ntawd, tus naj npawb ntawm zeros ntawm ib tug polynomial yeej ib txwm tsawg dua los yog sib npaug rau degree ntawm lub polynomial. Yog li ntawd, tus naj npawb ntawm cov txiaj ntsig tsis suav nrog cov lus qhia muaj txiaj ntsig tsis tuaj yeem tshaj li qib ntawm tus lej
Lub hauv paus ntsiab lus Aufbau ua haujlwm li cas uas txhais tau hais tias orbitals tau sau los ntawm hauv qab los yog saum toj saud nyob ntawm daim duab)?
Los ntawm Hauv qab Up: Cov chav yuav tsum tau sau los ntawm hauv av pem teb mus rau. Hauv pem teb siab dua qhov kev txiav txim yuav hloov me ntsis. Aufbau Txoj Cai: cov electrons sau cov orbitals ntawm lub zog qis tshaj mus rau lub zog siab tshaj. Nyob rau hauv lub xeev av tag nrho cov electrons nyob rau hauv qis tshaj tau lub zog theem
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Dab tsi yog zaj lus qhia ntawm Cyprus sim piav qhia los ntawm Mustapha Mond?
Dab tsi yog zaj lus qhia ntawm Cyprus sim piav qhia los ntawm Mustapha Mond? Ib haiv neeg ntawm Alphas tsis ua haujlwm. Lub neej ntawm Savage Reservation tuaj yeem rhuav tshem txhua qhov kev txias txias. Kev zoo siab yog tib txoj hauv kev rau kev vam meej ntawm tib neeg
