What is the trend in the basic character of Lanthanoid hydroxides ( to ) and why?
Basic character decreases. Due to Lanthanoid contraction, cation size decreases, increasing the covalent character of the M-OH bond.

In the 3d series, which element has the lowest enthalpy of atomization and why?.
Why is the melting point of Manganese (Mn) anomalously low compared to its neighbors?.
Why do the atomic radii of the second (4d) and third (5d) transition series exhibit very similar values (e.g., Zr ≈ Hf)?.
Why is the first Ionisation Enthalpy (IE) of Zn higher than expected, while Cr is lower?.
