  1. Decreases
  2. Increases
  3. First decreases then increases
  4. Remains constant
Show answer and solution

Correct answer: A. Decreases

1. These are halogens going down Group 17. 2. Down a group, atomic size increases and the nucleus holds bonding electrons less tightly. 3. Hence electronegativity decreases from fluorine to iodine. _Source: RRB Group D CEN-02/2018 PYQ, Q.18._
