Ob lub ntsiab ntawm lub atom yog cov nucleus thiab huab ntawm electrons . Cov nucleus muaj qhov zoo them nqi thiab nruab nrab subatomic hais, whereas huab ntawm electrons muaj cov khoom me me uas tsis zoo.

Cov lus nug tseem yog, dab tsi yog qhov tseem ceeb ntawm lub atom?

Peb qhov tseem ceeb ntawm atom yog protons , neutrons , thiab electrons . Protons - muaj tus nqi zoo, nyob hauv lub nucleus , Protons thiab neutrons muaj ze li tib lub sijhawm electrons muaj ntau tsawg loj. Neutrons - Muaj tus nqi tsis zoo, nyob hauv lub nucleus.

Tsis tas li ntawd, peb hom sib txawv ntawm ib qho atom yog dab tsi? Cov peb lub ntsiab subatomic cov khoom uas form ib atom yog protons, neutrons, thiab electrons. Qhov chaw ntawm lub atom hu ua nucleus. Ua ntej, cia peb kawm me ntsis txog protons thiab neutrons, thiab tom qab ntawd peb yuav tham txog electrons me ntsis tom qab. Protons thiab neutrons tsim cov nucleus ntawm ib qho atom.

Hais txog qhov no, dab tsi yog ob feem ntawm cov lus nug atom?

Cov ntsiab lus hauv cov teeb no (17)

  • Atom. lub hauv paus particle uas tag nrho cov ntsiab yog tsim; lub hauv paus chav tsev ntawm cov teeb meem uas muaj ib tug ntom central nucleus surrounded los ntawm ib tug huab ntawm tsis zoo nqi electrons.
  • Element. daim ntawv yooj yim tshaj plaws ntawm cov khoom ntshiab.
  • Nucleus.
  • Hluav taws xob.
  • Neutron.
  • Proton.
  • Atomic naj npawb.
  • Tus naj npawb.

Qhov 2 qhov twg ua rau lub nucleus ntawm lub atom?

Lub nucleus ntawm ib lub atom yog tsim los ntawm protons thiab neutrons (ob hom baryons) koom nrog lub zog nuclear. Cov baryons no yog ntxiv los ntawm sub-atomic cov ntsiab lus uas hu ua quarks koom nrog kev sib cuam tshuam.
