Cov pawg ntawm subatomic particles yog me me. Es tsis txhob sau lawv qhov hnyav hauv kilograms, lawv cov txheeb ze pawg tau siv. Qhov sib txheeb loj ntawm ib tug proton yog 1, thiab ib tug particle nrog ib tug txheeb ze loj dua 1 muaj tsawg loj. Qhov loj ntawm electrons tsawg heev piv rau protons thiab neutrons.
Dab tsi subatomic particle ua rau pawg sib txawv?
Neutrons yog cov khoom nruab nrab uas muaj qhov loj me me dua li ntawm cov proton. Cov isotopes sib txawv ntawm tib lub caij muaj tib tus naj npawb ntawm protons tab sis txawv cov lej ntawm neutrons. Tus naj npawb ntawm cov isotope yog tag nrho cov nucleons (neutrons thiab protons collectively).
Dab tsi yog qhov atomic huab hwm coj sawv cev ntawm cov lus subatomic?
Lub SI lub npe hu ua atomic mass unit, abbreviated amu, yog siv los qhia cov huab hwm coj ntawm subatomic hais. Cov kws tshawb fawb muab txhua tus proton ib pawg ntawm 1 amu thiab cim 'p. ' Tag nrho cov protons zoo ib yam, tsis hais los ntawm hom twg lawv tuaj. Tag nrho cov atoms ntawm ib lub caij muaj tib tus naj npawb ntawm protons.
Qhov twg subatomic particle loj tshaj?
Neutron, nruab nrab subatomic particle uas yog ib feem ntawm txhua atomic nucleus tsuas yog hydrogen zoo tib yam. Nws tsis muaj hluav taws xob thiab qhov seem seem sib npaug rau 1.67493 × 10 - 27 kg-marginally ntau dua li ntawm cov proton tab sis ze li 1,839 sij hawmntau dua li cov electron.
Qhov twg particle muaj qis tshaj plaws?
Feem ntau ntawm cov atom yog pom nyob rau hauv lub nucleus, uas yog tsim los ntawm protons thiab neutrons. Ib feem ntawm lub atom nrog qhov loj tshaj plaws yog tus electron.
