How does metallic character change down a group?
AStays constant
BDecreases
CIncreases
DVaries randomly
Answer & Solution
Correct answer: C. Increases
1. Down a group, atomic radius grows so outer electrons are loosely held.
2. Atoms therefore lose electrons more easily, becoming more metallic.
3. Caesium is more metallic than sodium for this reason.
4. So metallic character increases down a group.
5. The opposite holds across a period.
