Answer 1

Answer:

ffffuuuucccckkkkuuuu

Answer 2

Explanation:

The halogen family is said to have high electron affinity along with good oxidizing agents and mostly non-metallic in nature. When one goes down in the group, the affinity too is said to go down. This means that it will impact the reactivity which too decreases with the decrease in the electron affinity. That is why fluorine is most reactive of all.
