Silicon Hauv silica daim ntawv 4 sigma daim ntawv cog lus yog li nws hybridization yog sp3.

Tsis tas li ntawd, yog SiO2 linear lossis khoov?

Cov lus teb yog C vim SiO 2 yog lub network khoom (quartz) ib yam li (pob zeb diamond thiab graphite) yog li thaum koj kos nws tawm, nws tsis heev. kab tawm ntawm 120, nws ua tau me ntsis khoov thiab yuav tsum yog ntawm 110.

Vim li cas SiO2 tetrahedral? Yog vim li cas loj heev qauv ntawm SiO 2 : cas SiO 2 , qhov loj ntawm silicon atom loj dua li carbon atom. Ntau cov pa oxygen atoms tuaj yeem ncig silicon atom. Tab sis thaum plaub oxygen atoms txuas nrog ib tug silicon atom ces a tetrahedral qauv tsim.

Ntawm no, qhov zoo li cas ntawm silicon dioxide?

Nws yog 3-dimensional network khoom uas txhua tus silicon atom yog covalently bonded nyob rau hauv ib tug tetrahedral yam rau 4 oxygen atoms.

Lewis qauv rau SiO2 yog dab tsi?

Cov Lewis qauv rau SiO2 yog ncaj ncaj. Koj yuav tsum tau tsim ob daim ntawv cog lus kom ua tiav octets rau tag nrho cov atoms. Si yog qhov tsawg tshaj plaws electronegative atom thiab mus ntawm qhov chaw ntawm lub Lewis qauv . For SiO2 Lewis qauv koj muaj tag nrho ntawm 16 valence electrons.
