The order of stability of the complexes of some of the ions carrying the same charge by differing in ionic radii decrease as the ionic radii increase.
`{:("ion",Cu^(+2),Fe^(+2),Fe^(+2),Mn^(+2)),("Ionic radii",0.69,0.78,0.83,0.91):}`
The complexes of `Cu^(+2)` are most stable while `Mn^(+2)` is least stable.
