MCQ
In general, the properties that decrease and increase down a group in the periodic table respectively are
  • A
    atomic radius and electronegativity
  • B
    electron gain enthalpy and electronegativity
  • ✓
    electronegativity and atomic radius
  • D
    electronegativity and electron gain enthalpy
✓

Answer

Correct option: C.
electronegativity and atomic radius
c
On moving down a group, electronegativity decreases and atomic radius increases for representative elements.
