Solution
The basicity of oxides and hydroxides of lanthanoids decreases with increase in atomic number due to lanthanoid contraction.
Explanation:
As the atomic number increases, the size of lanthanoid ions decreases due to lanthanoid contraction. Smaller ions hold hydroxide ions more tightly, making them less basic.
