Why are Zn, Cd, and Hg not considered transition elements?.

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?.
