Of the ions Zn2+ , Ni2+ and Cr3+ (atomic number Zn = 30, Ni = 28, Cr = 24):
Text Solution
Verified by ExpertsA
Valence shell electron configuration of 30Zn2+ is 3d1º 4sº. As there is no unpaired electrons for d–d transition, the solution of ions will be colourless. Valence shell electron configuration of 28Ni2+ is 3d8 4sº. As there are 2 unpaired electrons, there is d–d transition of electron, so the solution of ions will be coloured. Valence shell electron configuration of 24Cr3+ is 3d3 4sº. As there are 3 unpaired electrons, there is d–d transition of electron, so the solution of ions will be coloured.
