Yuav ua li cas cov ntsiab lus thiab atoms tsim thaiv txhua qhov teeb meem?
Atoms yog tsim los ntawm cov me me subatomic particles, peb hom ntawm cov uas tseem ceeb: cov proton, neutron, thiab electron. Tus naj npawb ntawm cov protons uas muaj txiaj ntsig zoo thiab tsis them nyiaj (" nruab nrab") neutrons, muab cov huab hwm coj mus rau lub atom, thiab tus naj npawb ntawm txhua tus hauv nucleus ntawm lub atom txiav txim lub caij.
