Answer

Explanation:

Step1: Recall periodic - trend rules

Ionization energy and electronegativity increase across a period and decrease down a group in the periodic table. Antimony (Sb) and iodine (I) are in the same period (Period 5). Iodine is to the right of antimony in the periodic table.

Step2: Analyze ionization energy

Since ionization energy increases across a period, and I is to the right of Sb, Sb has a lower first - ionization energy than I. Given I's first - ionization energy is 1008 kJ/mol, Sb's is lower.

Step3: Analyze electronegativity

Electronegativity also increases across a period. So, Sb has a lower electronegativity than I. Iodine has a higher tendency to attract bonding electrons.

Answer:

Sb has a lower ionization energy and a lower electronegativity than I.
