Protons thiab neutrons muaj zoo sib xws pawg , thaum electrons yog deb dua, kwv yees li 11800 npaug ntawm pawg . Protons yog raug nqi zoo, neutrons tsis muaj hluav taws xob, electrons yog raug nqi. Qhov luaj li cas ntawm cov nqi yog tib yam, lub cim yog opposite.
Kuj paub, ua li cas cov huab hwm coj ntawm protons thiab neutrons piv rau qhov loj ntawm electron?
Protons thiab neutrons muaj kwv yees li qub pawg , tab sis lawv ob leeg yog ntau ntau loj dua electrons (kwv yees li 2,000 npaug loj npaum li ib hluav taws xob ). Tus nqi zoo ntawm a proton yog sib npaug hauv qhov loj rau qhov tsis zoo nqi ntawm ib qho hluav taws xob.
Kuj Paub, qhov loj ntawm electron thiab proton yog dab tsi? Nuclear Binding Zog thiab pawg tsis xws luag
Particle | Qhov hnyav (kg) | Mass (Mev/c2) |
---|---|---|
1 atomic mass unit | 1.660540 x 10-27 kg | 931.5 MeV/c2 |
neutron | 1.674929 x 10-27 kg | 939.57 MeV/c2 |
proton | 1.672623x10-27 kg | 938.28 MeV/c2 |
hluav taws xob | 9.109390x 10-31 kg | 0.511 MeV/c2 |
Piv txwv li, puas protons thiab neutrons muaj tib lub loj?
Atomic Protons thiab neutrons muaj ntau kwv yees li tib pawg 1,67 × 10-24 grams. Txawm tias zoo sib xws hauv pawg , protons raug nqi zoo, thaum neutrons muaj tsis muaj nqi. Yog li ntawd, tus naj npawb ntawm neutrons nyob rau hauv ib qho atom contributes ho rau nws pawg , tab sis tsis rau nws tus nqi.
Yuav ua li cas cov nqi ntawm protons neutrons thiab electrons piv?
Protons thiab neutrons yog nyob rau hauv qhov chaw (nucleus) ntawm lub atom. Proton - qhov zoo; hluav taws xob - tsis zoo; neutron - tsis muaj nqi . Cov them rau tus proton thiab electron yog 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.
Pom zoo:
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
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Dab tsi yog cov nqi 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
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
