Tus qauv planetary tau npaj tseg los ntawm Rutherford, raws cov qauv siv hluav taws xob ua ntej, thiab cov ntsiab lus tseem ceeb yog [7]:
① Feem ntau qhov atom' s ntim yog qhov khoob.
② Hauv qhov nruab nrab ntawm qhov atom, muaj me me thiab ntom nucleus.
Txhua yam zoo ntawm lub atom yog nyob hauv lub nucleus, thiab yuav luag txhua qhov loj yog nyob hauv lub nucleus. Cov pa roj tsis zoo hloov mus ncig lub nucleus ntawm kev kub ceev hauv qhov chaw nuclear.
Nrog kev nce qib ntawm kev tshawb fawb, qhov tseeb tias linear spectrum ntawm hydrogen atoms qhia tau hais tias lub ntiaj chaw qauv tsis raug.
