Verified step by step guidance

Understand that the reactivity of halogens generally decreases as you move down the group in the periodic table. This means elements at the top are more reactive than those below them.

Recall that halogens are in Group 17 of the periodic table, and their reactivity is largely determined by their ability to gain an electron to achieve a full octet.

Recognize that Fluorine (F) is at the top of the halogen group, above Chlorine (Cl), Bromine (Br), and Iodine (I), making it the most reactive halogen.

Consider the atomic size and electronegativity: Fluorine has the smallest atomic radius and highest electronegativity, which means it attracts electrons more strongly and reacts more readily.

Conclude that among the given options, Fluorine (F) is the most likely to react with other elements due to its position in the periodic table and its electronic properties.
