Sulfur feem ntau tsim 2 daim ntawv cog lus , np. H2S, -S-S-compounds Qhov no yog vim nws 3p4 orbital. p-orbitals tso cai rau 6 qhov chaw kom puv, li no sulfur nyhav tsim 2 daim ntawv cog lus . Nws tuaj yeem "nthuav cov octet" raws li nws muaj 6 valence electrons, ua rau muaj kev tsim ntawm 6 daim ntawv cog lus.

Ib yam li ntawd, tej zaum koj yuav nug tias, Sulfur muaj pes tsawg daim ntawv cog lus?

ob daim ntawv cog lus

Tsis tas li ntawd, sulfur puas tuaj yeem muaj 4 daim ntawv cog lus? Phosphorus tuaj yeem tsim mus txog tsib covalent daim ntawv cog lus , raws li nyob rau hauv phosphoric acid (H3PO 4 ). Feem ntau vim nws qhov chaw sab hnub tuaj tshaj plaws yog qhov loj dua li cov pa oxygen, sulfur canform tsawg li ob covalent daim ntawv cog lus , zoo li hauv hydrogensulfide (H2S), los yog ntau li rau, xws li hauv leej faj trioxide (SO3los yog sulfuric acid (H2YOG 4 ):

Tib neeg kuj nug, leej twg puas muaj 6 daim ntawv cog lus?

Teb thiab piav qhia: Sulfur muaj peev xwm ua tau 6 daim ntawv cog lus vim nws tuaj yeem muaj lub plhaub expandedvalence; leej faj yog nyob rau lub sijhawm 3 ntawm Lub Sijhawm Teev Taw.

Puas muaj leej faj ua tau triple bonds?

Tsiv electrons los ntawm ib leeg khub ntawm lub davhlau ya nyob twg atoms mus rau daim ntawv ob lub triple daim ntawv cog lus . Atoms uas nyiam daim ntawv ntau daim ntawv cog lus yog C, N, P, O, thiab S. Hydrogenand halogens TSIS TAU daim ntawv ob npaug daim ntawv cog lus . Qee cov molecules zoo li leej faj dioxide muaj qhov nthuav kev sib raug zoo xwm txheej.
