Assign reasons for the following: (i) ...

Assign reasons for the following:
(i) Copper (I) ion is not known in aqueous solution.
(ii) Actinoids exhibit greater range of oxidation states than lanthanoids.

Text Solution

Verified by Experts

(i) Because copper (I) ion is unstable in aqueous solution and undergoes, disproportionation.
  (ii) Because of very small gap between `5f, 6d and 7s` orbitals in actinoids.
