Step 1: Understanding the Question:
Electronegativity is the tendency of an atom to attract a shared pair of electrons. The question asks which element possesses this property most strongly. Step 2: Detailed Explanation:
Electronegativity increases across a period (left to right) and decreases down a group (top to bottom).
This is because smaller atoms with higher effective nuclear charges attract electrons more strongly.
Fluorine (\(F\)) is located at the top of Group 17 (Halogens). It is the smallest atom with a very high nuclear pull for electrons.
According to the Pauling scale, Fluorine is assigned the maximum value of approximately \(4.0\). Step 3: Final Answer:
Fluorine is the most electronegative element in the periodic table.
