Question 1732
Which pair of elements illustrates the effect of lanthanoid contraction by having very similar atomic radii?
Question 1733
What is a direct consequence of the decrease in metallic radius and increase in atomic mass in the transition series?
Question 1734
Compared to the shielding provided by d-electrons, how effective is the shielding provided by 4f electrons?
Question 1735
How does the lanthanoid contraction affect the atomic radii of elements in the second and third transition series?
