Solution

Solution Steps

Step 1: Identify the Groups

Identify the groups of the highlighted elements in the periodic table. The highlighted elements are in groups 1, 2, 13, 14, 16, 17, and 18.

Step 2: Determine Ionic Character

The ionic character of a bond is determined by the difference in electronegativity between the two elements. The greater the difference, the more ionic the bond.

Step 3: Compare Electronegativity Differences

Compare the electronegativity differences between the pairs of groups provided in the options. The largest difference will be between an alkali metal (group 1) and a halogen (group 17).
