How did you come up for it justify thay as well ?
The one with highest charge will stay more hydrated.
Given ans is Cr, it's a boards question btw
Cr has half filled t2g orbital..thats why
Why not Ti then it has no unpaired e-,should be most stable??
I am pretty sure high hydration will do the trick.
