Atoms muaj peb yam yooj yim hais: protons, electrons, thiab neutrons. Lub nucleus (center) ntawm lub atom muaj cov protons (zoo them) thiab cov neutrons (tsis muaj nqi). Atoms muaj cov khoom sib txawv raws li cov kev npaj thiab tus naj npawb ntawm lawv cov ntsiab lus.
Nyob rau hauv no hais txog, dab tsi yog ib feem ntawm ib tug atom piav txog txhua?
Qauv Ntawm Cov Atom : Peb cov qauv tam sim no ntawm cov atom tuaj yeem muab faib ua peb pawg ntu - protons, neutron, thiab electrons. Txhua ntawm cov no ntu muaj cov nqi sib txuas, nrog cov protons nqa cov nqi zoo, cov hluav taws xob muaj qhov tsis zoo, thiab cov neutrons tsis muaj nuj nqis.
Ib yam li ntawd, qhov tseem ceeb ntawm lub atom nyob qhov twg? Nrog rau kev zam ntawm hydrogen, tag nrho atoms muaj peb lub ntsiab ntu . Cov ib feem ntawm atom yog protons, electrons, thiab neutrons. Ib tug proton yog zoo them thiab yog nyob nyob rau hauv lub center los yog nucleus ntawm lub atom . Cov hluav taws xob tsis zoo raug them thiab yog nyob nyob rau hauv rings los yog orbits spinning nyob ib ncig ntawm lub nucleus.
Ntawm no, 3 qhov tseem ceeb ntawm lub atom yog dab tsi?
Peb qhov tseem ceeb ntawm atom yog protons , neutrons , thiab electrons . Protons - muaj tus nqi zoo, nyob hauv lub nucleus , Protons thiab neutrons muaj ze li tib lub sijhawm electrons muaj ntau tsawg loj. Neutrons - Muaj tus nqi tsis zoo, nyob hauv lub nucleus.
Dab tsi yog qhov tseem ceeb ntawm atom?
Ob lub ntsiab ntawm ib qho atom yog lub nucleus thiab huab ntawm electrons . Lub nucleus muaj qhov zoo them nqi thiab nruab nrab subatomic hais, whereas huab ntawm electrons muaj cov khoom me me uas tsis zoo.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
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
Lub organelle twg ua haujlwm raws li qhov chaw xa ntawv ntawm lub xov tooj ntawm tes txheeb cov proteins thiab xa lawv mus rau lawv qhov chaw xav tau sab hauv lossis sab nraud ntawm tes?
Golgi Hais txog qhov no, dab tsi organelle yog lub luag haujlwm rau kev thauj mus los? endoplasmic reticulum (ER Qhov thib ob, cov proteins txav mus los ntawm lub cell li cas? Cov proteins txav mus los endomembrane system thiab raug xa tawm los ntawm lub ntsej muag trans ntawm Golgi apparatus nyob rau hauv thauj vesicles uas txav mus los cytoplasm thiab tom qab ntawd fuse nrog plasma membrane tso tawm protein ntau mus rau sab nraum lub cell .
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
