MCQ
Which of the following property displays progressive increase with the rise in atomic number across a period in the periodic table
  • ✓
    Electronegativity
  • B
    Electron affinity
  • C
    Ionization potential
  • D
    Size of the atom
✓

Answer

Correct option: A.
Electronegativity
a
(a) Both electronegativity and electron affinity increases.

This is because decrease in the size and increase in the nuclear charge. But electronegativity increases continuously.
