Answer

Explanation:

Step1: Recall periodic - trend of ionization energy

Ionization energy increases across a period. Sb and I are in the same period (Period 5), and I is to the right of Sb. So, Sb has a lower first - ionization energy than I.

Step2: Recall periodic - trend of electronegativity

Electronegativity increases across a period. Since I is to the right of Sb in the same period, I has a higher electronegativity than Sb.

Answer:

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