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 magnitude rau tus nqi tsis zoo ntawm ib hluav taws xob.

Tsis tas li ntawd, qhov loj ntawm electron thiab proton yog dab tsi?

Protons , neutrons, thiab electrons : Ob leeg protons thiab neutrons muaj ib pawg ntawm 1 amu thiab pom nyob rau hauv lub nucleus. Txawm li cas los xij, protons muaj tus nqi ntawm +1, thiab neutrons tsis raug them. Hluav taws xob muaj a pawg ntawm kwv yees li 0 amu, orbit lub nucleus, thiab muaj nqi ntawm -1.

Ib tug kuj yuav nug, nws yuav siv pes tsawg electrons kom sib npaug ntawm qhov loj ntawm ib tug proton? Piav: Lub loj ntawm ib tug proton yog 1.673 × 10-27 kg. Yog li ntawd, 1837 electrons muaj ib yam pawg ua as1 proton.

Yog li ntawd, qhov loj ntawm ib tug proton yog dab tsi?

Loj ntawm proton : Loj ntawm proton yog 1.0072766 a.m. los yog 1.6726 x 10-27 kg. Sib piv pawg : Proton yog 1837 lub sij hawm hnyav dua li ib qho hluav taws xob. Txoj hauj lwm hauv atom: Protons muaj nyob rau hauv lub nucleus ntawm atom.

Dab tsi muaj qhov loj ntawm 1 amu?

Lub atomic mass unit (symbolized AMU lossis amu) yog txhais raws li qhov tseeb 1/12 qhov loj ntawm ib qho atom ntawm carbon-12. Cov pa roj carbon-12 (C-12) atom muaj rau protons thiab rau neutrons hauv nws cov nucleus. Hauv cov ntsiab lus tsis meej, ib qho AMU yog qhov nruab nrab ntawm qhov proton so mass thiab neutron so mass.
