Why is K2Cr2O7 pARAMAGNETIC???

Dear Student, Your question is wrong , K2Cr2O7 is Diamagnetic , Because Here Oxidation Sate of Cr is +6 Configuration of Cr â€‹(atomic number = 24) is [Ar] 3d5 4s1 , Therefore, Configuration ofâ€‹ Cr+6 is [Ar] 3d0 , Which show absence of unpaired electron means paired electrons So we can say that K2Cr2O7 is Diamagneticâ€‹ not Paramagnetic Hope this helps!

Why is K₂Cr₂O₇pARAMAGNETIC???

Dear Student,

Your question is wrong , K₂Cr₂O₇ is Diamagnetic , Because Here Oxidation Sate of Cr is +6.
Configuration of Cr (atomic number = 24) is [Ar] 3d⁵ 4s¹^,
Therefore, Configuration of Cr⁺⁶ is [Ar] 3d⁰, Which show absence of unpaired electron means paired electrons.
So we can say that K₂Cr₂O₇is Diamagnetic not Paramagnetic.

Hope this helps!
