Question

In general, the properties that decrease and increase down a group in the periodic table respectively are:

• A. electron gain enthalpy and electronegativity
• B. electronegativity and atomic radius
• C. atomic radius and electronegativity
• D. electronegativity and electron gain enthalpy

Answer 1

The correct option is B electronegativity and atomic radius

Electronegativity decreases as we go down the group and atomic radius increases as we go down the group.
