Question

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

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

Answer 1

Answer: (B)

electronegativity and atomic radius.

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