Problem

The correct order of increasing electron affinity of the following elements is : a. O<S<F<Cl\text{O} < \text{S} < \text{F} < \text{Cl} b. O<S<Cl<F\text{O} < \text{S} < \text{Cl} < \text{F} c. S<O<F<Cl\text{S} < \text{O} < \text{F} < \text{Cl} d. S<O<Cl<F\text{S} < \text{O} < \text{Cl} < \text{F}
Intuitive explanation

Electron affinity measures how eagerly an atom grabs an extra electron—more negative values mean stronger attraction. The key is recognizing that elements with nearly-full valence shells (like halogens) crave electrons most, while those with stable or half-filled configurations resist them. Scan the periodic table position and electron configuration of each element to predict their relative hunger for electrons.
