The d-And-f-Block Elements
Knowing that the Chemistry of lanthanoids (Ln) is dominated by its +3 oxidation state, which of the following statements in incorrect
The ionic sizes of Ln (III) decrease in general with increasing atomic number.
Ln (III) compounds are generally colourless.
Because of the large size of the Ln (III) ions, the bonding in its compounds is predominantly ionic in character
Ln (III) hydroxides are mainly basic in character.
B.
Ln (III) compounds are generally colourless.
Most of the Ln(III) compounds are coloured due to f – f transition.

How would you account for the irregular variation of ionisation enthalpies (first and second) in the first series of the transition elements?
