Raws li VSEPR Txoj Kev Xav (Valence Plhaub ElectronPairRepulsion Theory) cov huab cua hluav taws xob ntawm cov atoms thiab ib leeg ib leeg ib ncig ntawm P atom yuav tawm tsam ib leeg. Yog li ntawd lawv yuav raug thawb sib nrug muab rau PH 3 molecule atrigonalpyramidal geometry los yog puab.

Tsis tas li ntawd, dab tsi yog qhov molecular geometry ntawm ph3?

Raws li VSEPR txoj kev xav, lub geometry ntawm PH 3 molecule yog qhov zoo tshaj plaws piav raws li: linear, trigonalplanar, tetrahedral, khoov, lossis trigonal pyramidal.

Ib sab saum toj no, cov duab ntawm phosphine yog dab tsi? Peb piav qhia txog molecular geometry ntawm lub hauv paus ntawm atoms, sowhile electron khub xav tias tetrahedral puab Ib puag ncig phosphorus, geometry ntawm cov molecule ispyramidal, isostructural nrog ammonia.

tus qauv ntawm ph3 yog dab tsi?

Yog li cas PH 3 , P muaj 5 (valence electrons), ntxiv rau 3H monovalent atoms, thiab faib lawv los ntawm ob, yog li answercame4(sp3).. Thiab sp3 tsis muaj ib khub yog tetrahederal zoo li tus, sp3 nrog ib leeg yog pyramidal zoo li tus.. Yog li cas PH 3 , ans yog sp3 nrog ib leeg ib khub ces nws yog pyramidalshaped..

Puas yog ph3 trigonal pyramidal?

Lub molecular geometry ntawm PH3 yog trigonalpyramidal.
