Question

Which group contains the most electronegative elements in the periodic table?

• A. Group 1
• B. Group 2
• C. Group 16
• D. Group 17

Hint:

Electronegativity increases across a period and decreases down a group. Fluorine (Group 17) has the highest electronegativity among all elements.

Answer 1

The Correct Option is D

Concept: Electronegativity is the tendency of an atom to attract shared electrons in a chemical bond. Across a period, electronegativity increases from left to right, while down a group it generally decreases.

Step 1: Observe the trend across the periodic table. Elements on the right side of the periodic table have higher electronegativity.

Step 2: Identify the group with the highest values. Group 17 elements (halogens) such as fluorine, chlorine, bromine, and iodine have very high electronegativities.

Step 3: Note the most electronegative element. Fluorine, which belongs to Group 17, is the most electronegative element in the periodic table.
