Question

Out of chlorine and iodine, which one has strong non-metallic character?​

Answer 1

Explanation:

Metallic character tends to increase downwards, since the lower halogens are less electronegative than the ones closer to F.

That is reflected in that:

F is a gas (Tbp=−188.1∘C),

Cl is a denser gas (3.2 g/L vs. 1.696 g/L),

Br is a liquid (Tmp=−7∘C, Tbp=58.8∘C),

I is a solid (Tmp=113.7∘C),

and At is denser than I (formally a nonmetal, but denser than a solid!).

Metallic character tends to increase leftwards, since electronegativity tends to decrease leftwards on the periodic table.

Hence, Li is more of a metal than N, which is obvious, because N2 is a gas in natural conditions, and Li is literally of the "alkali metal" class.

Answer 2

Answer:

Iodine because non metallic character increases Left to right in period also down the group.
