Single Choice

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

Aelectronegativity and electron gain enthalpy.
Belectronegativity and atomic radius.
Correct Answer
Catomic radius and electronegativity
Delectron gain enthalpy and electronegativity

Solution

Electronegativity decrease as we go down the group and atomic radius increase as we go down the group.
