Proton - qhov zoo; hluav taws xob - tsis zoo; neutron - tsis muaj nqi . Cov nqi ntawm proton thiab hluav taws xob raws nraim qhov loj me tab sis opposite. Tib tus naj npawb ntawm protons thiab electrons raws nraim tso tseg ib leeg nyob rau hauv ib tug nruab nrab atom.
Raws li txoj cai, tus nqi ntawm proton yog dab tsi?
Proton Charge Thaum lub proton muaj tus nqi ntawm +1, lossis 1e, ib qho hluav taws xob muaj nqi ntawm -1, lossis -e, thiab a neutron tsis muaj nqi, lossis 0e. 1 theem pib nqi yog sib npaug rau: 1.602 x 10^-19 coulombs.
dab tsi yog cov nqi ntawm electrons? Charge ntawm Electron . Cov nqi ntawm hluav taws xob yog sib npaug rau qhov loj ntawm lub elementary nqi (e) tab sis coj tus cwj pwm tsis zoo. Txij li tus nqi ntawm cov theem pib nqi yog 1,602x10-19 coulombs (C), ces tus nqi ntawm hluav taws xob yog -1,602x10-19 C.
Nyob rau hauv no txoj kev, dab tsi yog tus nqi nyob rau hauv ib tug neutron?
A neutron , zoo li lub npe implies, yog nruab nrab tsis muaj net nqi . Cov nqi ntseeg tau los ntawm nqi ntawm cov quarks uas tsim cov nucleons (protons thiab neutrons ). Ib tug proton yog ua los ntawm ob lub Up quarks, nrog 2/3 zoo nqi Txhua tus thiab ib qho Down Quark nrog qhov tsis zoo 1/3 nqi (2/3 + 2/3 + -1/3 = 1).
Protons neutrons electrons yog dab tsi?
Cov ntsiab lus. Hluav taws xob yog ib hom subatomic particle uas muaj tus nqi tsis zoo. Protons yog ib hom subatomic particle nrog ib tug zoo nqi. Protons tau khi ua ke hauv ib qho atom lub nucleus vim yog lub zog muaj zog nuclear. Neutrons yog hom subatomic particle uas tsis muaj nqi (lawv nyob nruab nrab).

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
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
Qhov loj ntawm protons thiab neutrons thiab electrons piv li cas?
Protons thiab neutrons muaj huab hwm coj zoo sib xws, thaum electrons nyob deb dua, kwv yees li 11800 npaug ntawm qhov loj. Protons raug them zoo, neutrons tsis muaj hluav taws xob, electrons tsis zoo. Qhov luaj li cas ntawm cov nqi yog tib yam, lub cim yog opposite
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
Dab tsi yog cov yam ntxwv ntawm protons neutrons thiab electrons?
Proton - zoo; electron-tsis zoo; neutron - tsis muaj nqi. Tus nqi ntawm cov proton thiab electron yog tib yam nkaus tab sis txawv. Tib tus naj npawb ntawm protons thiab electrons raws nraim tshem tawm ib leeg hauv ib qho nruab nrab atom
