Ib lub atom muaj ib lub hauv paus nucleus uas feem ntau nyob ib puag ncig los ntawm ib lossis ntau dua electrons Txhua lub tshuab hluav taws xob tsis zoo. Lub nucleus yog qhov zoo, thiab muaj ib lossis ntau qhov hnyav uas hu ua protons thiab neutrons. Ib tug proton raug nqi zoo.
3 yam twg yog ib qho atom ua los ntawm?
Structure: Peb cov qauv tam sim no ntawm atom tuaj yeem tawg ua peb qhov chaw - protons, neutron, thiab electronsTxhua qhov ntawm cov khoom no muaj cov nqi cuam tshuam, nrog cov protons nqa. tus nqi zoo, electrons muaj qhov tsis zoo, thiab cov neutrons tsis muaj nuj nqis.
Atom tsis muaj dab tsi?
Atoms tsis tas yuav muaj tib tus lej ntawm electrons thiab protons, txawm tias lub xeev no muaj ntau. Thaum ib lub atom muaj pes tsawg tus electrons thiab protons, nws muaj qhov sib npaug ntawm cov nqi hluav taws xob tsis zoo (cov electrons) thiab cov nqi hluav taws xob zoo (protons).
Vim li cas nws tseem ceeb kom paub cov qauv ntawm ib lub atom?
Raws li kev ua haujlwm los ntawm cov kws tshawb fawb yav dhau los ntawm cov qauv atomic, cov kws tshawb fawb tam sim no muaj lub tswv yim zoo ntawm lub atom zoo li cas. Qhov kev paub no tseem ceeb vim nws pab peb nkag siab tias vim li cas cov ntaub ntawv muaj cov khoom sib txawv thiab vim li cas qee cov ntaub ntawv sib raug zoo nrog lwm tus
Atom puas muaj nyob tsis muaj neutrons?
Tsuas muaj ib qho atom ruaj khov uas tsis muaj neutrons. Nws yog ib qho isotope ntawm lub caij hydrogen hu ua protium. Protium, uas muaj ib qho proton thiab ib qho hluav taws xob, yog lub atom yooj yim tshaj plaws. Tag nrho lwm cov atom ruaj khov muaj qee tus lej ntawm neutrons.
