In Group 6, why is Cr(VI) a strong oxidizing agent while Mo(VI) and W(VI) are stable?.
Heavier d-block members favor higher oxidation states. Thus, Mo(VI) and W(VI) are stable, while Cr(VI) is unstable and reduces easily.

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?.
