actinide colour and complex formation
Answers
Actinides ions are usually colored. The color depends upon the number of 5f electrons, ions with 5f 0 electrons and 5f 7 electrons are colorless. The color is due to f-f electronic transitions.
==>Complex formation of Actinide elements
The degree of complex formations decreases in the order:
An+4 > AnO2 +2 > An+3 > AnO2 +
The complexing power of different singly charged and doubly charged anions follows the order:
Singly charged anions: F- > No3 - > Cl-
Doubly charged anions: Co3 -2 > Ox-2 > So4 -2
Actinides also form complexes with a large number of organic substances.
