Lub Atom Balanced

Feem ntau cov nuclei kuj muaj cov neutrons. Tej zaum qhov tseem ceeb tshaj plaws yam ntxwv ntawm a proton yog nws cov nqi hluav taws xob zoo. Tus nqi no sib npaug ntawm qhov loj me rau qhov tsis zoo ntawm cov hluav taws xob hluav taws xob, uas txhais tau hais tias tus nqi ntawm ib qho proton balances tus nqi ntawm ib tug electron.

Ib yam li ntawd, cov yam ntxwv ntawm electrons yog dab tsi?

Hluav taws xob yog cov tsis zoo them nqi ntawm atom. Ua ke, tag nrho cov electrons ntawm ib qho atom tsim cov nqi tsis zoo uas sib npaug qhov zoo ntawm cov protons hauv atomic nucleus. Hluav taws xob yog me me heev piv rau tag nrho lwm qhov ntawm lub atom.

Ib sab saum toj no, dab tsi yog qhov txawv ntawm electrons protons thiab neutrons? 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).

Ntawm no, cov yam ntxwv ntawm neutrons yog dab tsi?

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 × 1027 kg-marginally ntau dua li ntawm cov proton tab sis ze li ntawm 1,839 npaug ntau dua li ntawm cov electron.

Dab tsi yog tus yam ntxwv ntawm lub atom?

Atoms . Atoms yog cov feem tsawg tshaj plaws ntawm ib lub caij uas tuaj yeem muaj nyob, thiab tseem qhia tau tias yam ntxwv ntawm lub ntsiab. Atoms lawv tus kheej yog tsim los ntawm electrons (1 tsis zoo xwb), protons (1 zoo xwb), thiab neutrons (tsis muaj nqi).
