Question

Identify correct orders with respect to properties:
I. B < Al < Mg < K (metallic character)
II. Si < P < C < N (electronegativity)
III. Si < C < N < F (non-metallic character)
IV. Al < Mg < S < P (ionization enthalpy)

• A. I, II, III only
• B. II, III, IV only
• C. I, III only
• D. I, II, III, IV

Hint:

Across a period: electronegativity and ionization enthalpy increase.
