Dear nitin,

Total Number of electron pairs Arrangement of electron pairs Number of bonding pairs of electrons Number of lone pairs of electrons Shape of Molecule Name of Shape Bond Angle Examples
not applicable linear 1 not applicable linear 180o H2, HCl
2 linear 2 0 linear 180o CO2, HCN
3 trigonal planar 3 0 triganol planar 120o BCl3, AlCl3
4 tetrahedral 4 0 tetrahedral 109.5o CH4, SiF4
3 1 trigonal pyramidal <109.5o (bond angles in ammonia, NH3, are 107o) NH3, PCl3
2 2 bent <109.5o (bond angles in water, H2O, are 105o) H2O, SCl2
5 trigonal bipyramidal 5 0 trigonal bipyramidal 120o in the trigonal planar part of the molecule, 90o for the others PCl5
6 octahedral 6 0 octahedral 90o SF6

I want to know, Effective atomic number of Cu2+ion in CuSO4.5H2O complex, how to calculate ?
EAN = metal electrons + Ligands + Charge and Electronic configuration of Cu2+ = 1s2 2s2 2p6 3s2 3p6 4s0 3d9 Hence, => 9 + (5 + 1) + 2 = > 17. that would be the EAN number perhaps for Cu2+.
