Tus nqi qis, feem ntau txhais los ntawm e lossis qee zaum qₑ yog tus nqi hluav taws xob nqa los ntawm ib qho proton lossis, sib npaug, qhov loj ntawm qhov tsis zoo hluav taws xob nqa los ntawm ib qho hluav taws xob, uas muaj nqi −1 e. Tus nqi qis no yog qhov tseem ceeb ntawm lub cev tsis tu ncua.
Tus nqi ntawm electrons yog dab tsi?
Electron charge, (cim e), lub cev tseem ceeb tas mus li qhia qhov tshwm sim ntawm lub cev hluav taws xob, sib npaug rau 1.602176634 × 10 - 19
Dab tsi yog tus nqi ntawm electron zoo lossis tsis zoo?
Protons thiab Electrons
Ib tug proton nqa tus nqi zoo (+) thiab tus electron nqa tus nqi tsis zoo (-), yog li cov atoms ntawm cov ntsiab lus nruab nrab, tag nrho cov nqi zoo tshem tawm tag nrho cov nqi tsis zoo. Atoms txawv ntawm ib leeg nyob rau hauv tus naj npawb ntawm protons, neutrons thiab electrons lawv muaj.
Puas muaj hluav taws xob muaj nqi?
Electrons muaj tus nqi tsis zoo. Tus nqi ntawm cov proton thiab electron yog tib yam loj tab sis txawv. Neutrons tsis muaj nqi. Txij li cov nqi sib txawv nyiam, protons thiab electrons nyiam ib leeg.
Dab tsi yog qhov tsis muaj nqi?
Neutron , nruab nrab subatomic particle uas yog ib feem ntawm txhua atomic nucleus tsuas yog hydrogen zoo tib yam. Nws tsis muaj nqi hluav taws xob thiab qhov seem loj sib npaug rau 1.67493 × 10 -27 kg-marginally ntau duatshaj li ntawm cov proton tab sis ze li ntawm 1,839 npaug ntau dua li ntawm cov electron.
