4 cards from this section. Quick, good the night before a test.
What is atomic radius?
Consider what defines the size of an atom.
Define lanthanoid contraction.
Think about how nuclear charge affects size.
What is lanthanoid contraction?
Think about what happens to size as you move across the series.
True or False: Ionic sizes increase as you go from lanthanum to lutetium.
Recall the trend of decreasing sizes in the lanthanide series.
Given the ionic radii of cerium (IV) and lutetium (III), analyze the differences in their reactivity based on ionic size.
Factor in how charge density influences ion interactions.
Explore the impact of lanthanoid contraction when comparing the separation of gadolinium and dysprosium during industrial processes.
Consider methods that exploit subtle reactivity differences in close-sized elements.
