Question:medium

Knowing that the chemistry of lanthanoids (Ln) is dominated by its +3 oxidation state, which of the following statements is incorrect?

Show Hint

Colour in lanthanoids arises from: f--f electronic transitions

Updated On: Mar 19, 2026

The ionic size of Ln(III) decreases in general with increasing atomic number
Ln(III) compounds are generally colourless
Ln(III) hydroxide are mainly basic in character
Because of the large size of the Ln(III) ions the bonding in its compounds is predominantly ionic in character
