EAN of copper in cuprammonium sulphate is:
Cuprammonium sulphate is Tetraamminecopper sulphate.
[Cu(NH3)4]SO4
Effective atomic number of Cu in [Cu(NH3)4]2+ can be calculated as :
EAN = Number of electron in divalent Cu ( atomic number - charge) + number of bonding electron from surrounding ammonia ligand (each contributes an electron pair)
EAN = 27 + 8 = 35
[Cu(NH3)4]SO4
Effective atomic number of Cu in [Cu(NH3)4]2+ can be calculated as :
EAN = Number of electron in divalent Cu ( atomic number - charge) + number of bonding electron from surrounding ammonia ligand (each contributes an electron pair)
