Electrons are most loosely bound in which of the following halogen?
Correct answer: A. Iodine
- A. Iodine
- B. Bromine
- C. Chlorine
- D. Fluorine
Explanation
Iodine (I) has the largest atomic size among the given halogens. As atomic size increases, the outermost electrons are farther from the nucleus and experience weaker attraction. This makes the electrons in iodine more loosely bound compared to the other halogens.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
