Group 16 Group 17

- -

- A

- -

B C

b) State whether $C$ is more reactive or less reactive than $A$ .

Solution

$C$ is less reactive than $A$ .
Elements A and C belong to same group (halogens). Reactivity of halogens decreases as we go down the group. Element at the top (Fluorine) is the most reactive element amongst all halogens.
