Molecular Strucutre
Can someone check these?
Formula - Total # of electron pairs on central atom - # of bonded - # of non-bonded - Electron Geometry - Molecular Goemetry
^ that's the sequence...
SiH4 - 4 - 4 - 0 - tetrahedral - tetrahedral
PCl3 - 4 - 3 - 1 - tetrahedral - trigonal pyramidal
BF3 - 3 - 3 - 0 - trigonal planar - trigonal planar
SeCl2 - 4 - 2 - 2 - tetrahedral - v shaped
SF6 - 6 - 6 - 0 - octahedral - octahedral
CO2 - 4 - 4 - 0 - linear - linear
XeF2 - 5 - 2 - 3 - trigonal bipyramidal - linear
NO3- - 4 - 4 - 0 - trigonal planar - trigonal planar
NO2- - 4 - 3 - 1 - trigonal planar - v shaped
ClF3 - 5 - 3 - 2 - trigonal bipyramidal - T shaped
AsF3 - 4 - 3 - 1 - tetrahedral - trigonal pyramidal
SF4 - 5 - 4 - 1 - trigonal bipyramidal - seesaw
All of these look ok to me. Good work. And it's a LOT of work.
