Which property INCREASES down a group?
AMetallic character
BElectronegativity
CIonisation energy
DNon-metallic character
Answer & Solution
Correct answer: A. Metallic character
1. Down a group, atoms become larger with more shells.
2. Outer electrons feel a weaker nuclear pull from the inner shells.
3. So atoms lose electrons more easily, raising metallic character.
4. Ionisation energy, electronegativity and non-metallic character all decrease.
