Why Is fluorine the most reactive halogen?

Fluorine:

• Fluorine is the lightest halogen element and the most reactive chemical element.
• Because of its great propensity to attract electrons and the small size of its atoms, it has high chemical activity.

Halogen with the highest level of reactivity:

• Fluorine has the shortest atomic size of all the halogens. As a result, the nuclear attraction on the furthest electrons is greatest.
• Among the halogens, fluorine is the most reactive.
• Group seven's most reactive element, fluorine, is significantly more reactive than chlorine. The outer shell of fluorine is closer to the nucleus and has fewer filled spaces.
