Atomic Qauv. Ib atom muaj qhov zoo raug them nucleus, ncig los ntawm ib lossis ntau qhov tsis zoo raug them cov khoom hu ua electrons. Qhov zoo nqi sib npaug qhov tsis zoo nqi , yog li ntawd atom tsis muaj tag nrho nqi ; nws yog hluav taws xob nruab nrab. Lub nucleus ntawm ib atom muaj protons thiab neutrons.

Hauv qhov no, vim li cas atoms tsis muaj hluav taws xob?

Vim li cas atoms tsis muaj hluav taws xob txawm tias feem ntau ntawm lawv cov khoom muaj nqi ? Atoms tsis muaj hluav taws xob vim hais tias cov protons thiab electrons "tso tawm" ib leeg nqi . Neutrons tsis muaj nqi.

Ib tug kuj yuav nug, puas yog lub atom puas muaj hluav taws xob? Protons thiab electrons tsim hluav taws xob teb. Feem ntau hluav taws xob nqi yog nqa los ntawm electrons thiab protons nyob rau hauv ib atom . Cov hluav taws xob tau hais tias nqa tsis zoo nqi , thaum protons tau hais tias nqa qhov zoo nqi , txawm hais tias cov ntawv no yog qhov tsis txaus ntseeg (ntxiv rau tom qab ntawd).

Ntxiv rau qhov no, qhov twg ntawm lub atom tsis muaj hluav taws xob?

Protons nqa qhov zoo hluav taws xob , electrons nqa ib tug tsis zoo hluav taws xob thiab neutrons nqa tsis muaj hluav taws xob tag nrho. Cov protons thiab neutrons pawg ua ke hauv nruab nrab ib feem ntawm atom , hu ua nucleus, thiab cov electrons 'orbit' lub nucleus.

Dab tsi yog atomic mass number?

Cov pawg naj npawb (Symbol A, los ntawm German lo lus Atomgewicht [ atomic luj]), kuj hu ua atomic loj naj npawb los yog nucleon tus lej , yog tag nrho tus lej ntawm protons thiab neutrons (ua ke hu ua nucleons) hauv ib atomic nucleus. Cov pawg naj npawb Nws txawv rau txhua qhov sib txawv ntawm cov isotope ntawm cov khoom siv tshuaj.
