How do I figure out thr number of electron groups in a molecule? I thought it was the number of atoms around the central atom but for some cases it isnt right.
For SnCl2, is it 2 electron groups.
For H2O2, how would I figure that out, since both oxygens are the central atoms, would it be two?

You need to explain what you mean by electron groups. Are you talking about "regions of high electron density"?
I mean how many electron groups to determine the shape of it...VSEPR
Yes, you are talking about regions of high electron density.
2 linear
3 trigonal planar
4 tetrahedral
5 trigonal bipyramid
6 octahedral
