A neutron yog ib tug subatomic particle pom nyob rau hauv lub nucleus ntawm atoms uas txawv ntawm lwm subatomic hais (hu ua protons) nyob rau hauv lub nucleus ntawm atoms vim hais tias neutrons tsis muaj (zero) nqi thaum txhua tus proton muaj tus nqi zoo ntawm +1.
Ntxiv mus, dab tsi yog qhov yooj yim neutron txhais?
Kuj saib electron. A neutron yog ib tug subatomic particle pom nyob rau hauv lub nucleus ntawm txhua lub atom tsuas yog hais tias ntawm yooj yim hydrogen. Cov khoom siv tau muab nws lub npe los ntawm qhov tseeb tias nws tsis muaj hluav taws xob; nws yog nruab nrab. Neutrons yog tuab heev. Tus naj npawb ntawm proton nyob rau hauv ib lub ntsiab ntawm lub nucleus yog hu ua tus naj npawb atomic.
Tsis tas li ntawd, lub hom phiaj ntawm neutrons yog dab tsi? Qhov ntxiv attraction ntawm lub neutrons ua kom cov protons cov nqi hluav taws xob los ntawm kev rhuav tshem cov atomic nucleus sib nrug. Yog li vim li cas neutrons yog tso cai rau ntau tshaj ib tug proton nyob rau hauv ib tug atomic nucleus.
Hauv qhov no, txhais li cas ntawm electron hauv chemistry?
hluav taws xob . Yog koj noj chemistry , koj yuav kawm txog electrons . Hluav taws xob yog qhov tsawg tshaj plaws ntawm cov khoom uas tsim ib lub atom, thiab lawv nqa ib tug tsis zoo nqi. Tus naj npawb ntawm protons thiab electrons yog sib npaug hauv ib qho nruab nrab atom. Piv txwv li, hydrogen atom muaj ib qho xwb hluav taws xob thiab ib tug proton.
Dab tsi yog 3 ntu ntawm neutron?
Peb qhov tseem ceeb ntawm atom yog protons, neutrons , thiab electrons. Protons - muaj ib tug zoo nqi, nyob rau hauv lub nucleus, Protons thiab neutrons muaj ze li qhov loj tib yam thaum electrons muaj tsawg dua loj. Neutrons - Muaj cov nqi tsis zoo, nyob hauv lub nucleus.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov txawv ntawm qhov kaw kaw thiab qhib qhov system hauv chemistry?
Ib puag ncig yog txhua yam tsis nyob hauv qhov system, uas txhais tau tias tag nrho ntawm lub ntiaj teb. Qhov no yog hu ua qhib qhov system. Yog tias tsuas muaj kev sib pauv cua sov tshwm sim ntawm qhov system thiab nws qhov chaw nyob ib puag ncig nws yog hu ua kaw kaw. Tsis muaj teeb meem tuaj yeem nkag lossis tawm hauv qhov kaw
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
