Which statement describes the general trends in electronegativity and first ionization energy as the elements in period 3 are considered

Question

Which statement accurately describes the general trends in electronegativity and first ionization energy as the elements in Period 3 are considered in order from sodium (Na) to chlorine (Cl)? (1) Electronegativity increases, and first ionization energy decreases. (2) Electronegativity decreases, and first ionization energy decreases. (3) Both electronegativity and first ionization energy increase. (4) Both electronegativity and first ionization energy decrease.

Correct  (3) Electronegativity and first ionization energy both increase.Reason:Electronegativity and ionization energy are dependent on effective nuclear charge and size of atom.As we move along the periodic table from left to right, atomic size decreases and effective nuclear charge increases. The increase in effective nuclear charge and decrease in atomic radii favor ionization energy and electronegativity. Hence, in 3rd period (from Na to Cl) electonegativity and 1st ionization energy increases.
