There was another question paper also asking for the shape of d-orbitals of metal cation in a complex ion. I know that three of them are on lower energy level and the other two on higher.
The normal shape of even-energy d-orbitals... I heard someone said they are like double-dumbbells.

ASA,
Can anyone explain the chromatography thing? like what is the stationary phase? what is the mobile phase? what are the two types of seperation techniques used in chromatography, like adsobtion and partition?
I have read it many times in the support booklet and in Chemguide but still can't understand it.. any help would be greatly appreciated!
