Question

The most electronegative element among the following is:

• A. Sodium
• B. Bromine
• C. Fluorine
• D. Oxygen

Hint:

This element sits at the top right of the periodic table, just before the noble gases.

Answer 1

The Correct Option is C

Step 1: Recall the periodic trend.
Electronegativity generally increases across a period from left to right and decreases down a group.
Step 2: Locate fluorine.
Fluorine is in period 2, group 17, at the top right region of the periodic table, just before the noble gases. This position gives it the smallest atomic size and the strongest pull on shared electrons among all elements.
Step 3: Compare with the other options.
Sodium is a highly electropositive alkali metal, it loses electrons rather than attracting them. Bromine and oxygen are both electronegative, but they lie below or to the left of fluorine's position, so their pull on electrons is weaker than that of fluorine.
Final Answer: C) Fluorine.
