Tab sis ib tug proton thiab ib electron nyiam ib leeg . Lwm tus txoj kev hais no yog qhov ntawd tus tib yam los yog "zoo li" tsub tawm ib qho lwm thiab cov nqi them rov qab nyiam ib lwm . Txij li cov nqi sib txawv sib nyiam , tus tsis zoo nqi electrons yog nyiam rau tus zoo them protons.

Ib yam li ntawd, puas electrons nyiam lossis sib ntaus sib tua?

Ob electrons yuav nyiam ntxeev siab rau ib leeg vim ob leeg muaj qhov tsis zoo hluav taws xob. Ob tug protons kuj yuav nyiam ntxeev siab rau ib leeg vim nkawd ob leeg muaj tus nqi zoo. Nyob rau lwm yam tes, electrons thiab protons yuav yog nyiam rau ib leeg vim lawv tsis nyiam them nqi.

Tsis tas li ntawd, 2 puas tuaj yeem nyiam cov nqi sib tw? Nyob rau hauv sib piv rau lub zog txaus nyiam ntawm ob yam khoom nrog opposite nqi , ob yam khoom uas yog ntawm zoo li tus nqi yuav repel ib leeg . Ntawd yog, qhov zoo raug them khoom yuav exert ib tug repulsive quab yuam rau ib tug thib ob zoo raug them khoom.

Ib tug kuj yuav nug, dab tsi yog qhov attraction ntawm electrons?

Chemical bond yog hais txog lub zog tuav cov atoms ua ke los tsim cov molecules thiab solids. Lub zog no yog ntawm hluav taws xob xwm, thiab attraction ntawm electrons ntawm ib atom rau lub nucleus ntawm Lwm atom pab txhawb rau qhov hu ua chemical bonds.

Vim li cas tus nqi zoo thiab qhov tsis zoo nyiam ib leeg?

A tus nqi zoo thiab a tsis zoo nqi attracts ib leeg yog li ntawd thaum lawv yuav los ze thiab ntsib lawv yuav nruab nrab ib leeg (nyob rau hauv rooj plaub lawv qhov loj me yog tib yam, txwv tsis pub qhov loj ntawm net nqi yuav txo qis) yog li txo qis lossis ploj ntawm lub zog hluav taws xob li no txo qis lub zog khaws cia.
