Fluorine
Lithium
Sodium
Calcium
Understanding the Answer
Let's break down why this is correct
Fluorine is at the top of the halogen group and has the smallest radius, so it pulls electron density the strongest. Other options are incorrect because Lithium is a metal with a large ionic radius and low electronegativity; Sodium is larger and has a single valence electron, making it easy to lose.
