  1. Kos cov nucleus.
  2. Sau tus naj npawb ntawm neutrons thiab tus naj npawb ntawm protons hauv lub nucleus.
  3. Kos thawj theem zog.
  4. Kos cov electrons hauv qib zog raws li cov cai hauv qab no.
  5. Nco ntsoov tias muaj pes tsawg tus electrons muab tso rau hauv txhua qib thiab pes tsawg tus electrons tshuav siv.

Ua raws li qhov no hauv kev xav, Bohr daim duab ua haujlwm li cas?

Bohr daim duab qhia cov electrons orbiting lub nucleus ntawm ib lub atom zoo li cov ntiaj chaw orbit ncig lub hnub. Hauv Bohr qauv , electrons yog duab raws li kev mus ncig hauv lub voj voog ntawm cov plhaub sib txawv, nyob ntawm seb koj muaj lub caij twg. Txhua lub plhaub tsuas tuaj yeem tuav qee tus lej ntawm electrons.

Ib yam li ntawd, muaj pes tsawg electrons nyob hauv lub plhaub? Txhua lub plhaub muaj peev xwm tsuas muaj tus naj npawb ruaj khov ntawm cov hluav taws xob: Thawj lub plhaub tuaj yeem tuav tau ob tug electrons , lub plhaub thib ob tuaj yeem tuav tau txog yim (2 + 6) electrons, lub plhaub thib peb tuaj yeem tuav tau 18 (2 + 6 + 10) thiab lwm yam. Cov qauv dav dav yog tias lub plhaub nth tuaj yeem tuav txog 2 (n2) electrons.

Raws li txoj cai, daim duab Bohr yog dab tsi?

Daim duab Bohr yog ib qho yooj yim pom kev sawv cev ntawm lub atom uas yog tsim los ntawm Danish physicist Niels Bohr nyob rau hauv 1913. Daim duab qhia txog lub atom raws li ib tug zoo nqi. nucleus nyob ib puag ncig electrons uas taug kev nyob rau hauv ncig orbits txog lub nucleus nyob rau hauv discrete zog theem.

Koj nyeem Bohr qauv li cas?

  1. Kos lub nucleus.
  2. Sau tus naj npawb ntawm neutrons thiab tus naj npawb ntawm protons hauv lub nucleus.
  3. Kos thawj qib zog.
  4. Kos cov electrons hauv qib zog raws li cov cai hauv qab no.
  5. Nco ntsoov tias muaj pes tsawg tus electrons muab tso rau hauv txhua qib thiab pes tsawg tus electrons tshuav siv.
