@ghazi  do you know anyone who is good is chemistry?

ghazi · Answer

dude..i have no specific idea...

anonymous · Answer

okay.. ps am a girl(goddess)

ghazi · Answer

it's so3^2- he he :)

anonymous · Answer

@radar please help

ghazi · Answer

see NH3 has one lone pair over it..and all the three N-H bond lie just below the plane...similarly SO3^2- has structure in which one lone pair lies above the surface

ghazi · Answer

SO3^2- has similar structure to that of NH3

anonymous · Answer

okay, you are right but how did you know that? is there something that I can use in the future?

anonymous · Answer

@ghazi

ghazi · Answer

there are three bond pair and one lone pair...and due to bond pair lone pair repulsion the planar structure of it is pressed down |dw:1345893128272:dw| similarly for SO3^2-
