Explanation:

The ability of an atom to attract shared electrons is measured by electronegativity. Electronegativity generally increases across a period and decreases down a group on the periodic table. Comparing the given atoms: I (iodine) is in group 17, period 5; H (hydrogen) has low electronegativity; N (nitrogen) is group 15, period 2; Li (lithium) is a group 1 metal with very low electronegativity; C (carbon) is group 14, period 2. Among these, nitrogen has a higher electronegativity than C, H, Li, and I (since I is lower in group 17 than F/Cl/Br, so less electronegative than N).

Answer:

O N
