Tom qab ntawd kuv kos lub Lewis dot qauv rau Aluminium ( Al ). Nco tseg: Aluminium yog nyob rau hauv Pawg 13 (qee zaus hu ua Pawg III lossis 3A). Txij li thaum nws nyob hauv Pawg 3 nws yuav muaj 3 valence electrons. Thaum koj kos lub Lewis qauv rau Aluminium koj yuav muab peb "dots" los yog valance electrons nyob ib ncig ntawm lub caij cim ( Al ).

Yog li ntawd, Lewis qauv rau Al yog dab tsi?

Teb: Txhuas yog nyob rau hauv pawg IIIA ntawm lub sij hawm lub sij hawm yog li ntawd nws muaj peb valence electrons . Lub cim rau txhuas yog Al uas yuav nyob ib puag ncig los ntawm peb qhov chaw. 2.

Tsis tas li ntawd, koj pom lub cim Lewis li cas? A Lewis Symbol yog tsim los ntawm kev tso cov dots sawv cev rau cov electrons nyob rau hauv lub zog sab nraud nyob ib ncig ntawm lub cim rau lub ntsiab. Rau ntau lub ntsiab lus, tus naj npawb ntawm cov dots sib haum mus rau lub ntsiab ntawm pawg naj npawb. Hauv qab no Lewis Symbols rau ntau yam. Daim ntawv ceeb toom cov ntawv xov xwm rau txhua lub ntsiab lus ntawm pab pawg naj npawb.

Yog li ntawd, lub cim Lewis yog dab tsi?

Lewis cov qauv (tseem hu ua Lewis dot structures lossis electron dot structures) yog cov duab kos uas sawv cev rau valence electrons ntawm atoms hauv ib lub molecule. Cov no Lewis cim thiab Lewis cov qauv pab pom qhov valence electrons ntawm atoms thiab molecules, txawm tias lawv muaj nyob hauv ib leeg lossis hauv cov ntawv cog lus.

Lewis dot qauv rau Na+ yog dab tsi?

Cov dots hauv Lewis dot qauv symbolize lub atom lub ntsiab. Txij li Na^+ yog qhov zoo ion (cation) nrog tus nqi ntawm +1, nws qhia tau tias nws tau poob ib qho hluav taws xob . Vim Na muaj ib tug hluav taws xob , pib nrog, thiab tam sim no ploj lawm, Na^+ yuav tsis muaj dots.
