Rank the nonmetals in each set from most reactive (1) to least reactive (3).

Question

Bromine:

Chlorine:

Iodine:

Answer 1

When ranking the reactivity of the halogens, the order from most reactive to least reactive is as follows:

1. Chlorine (most reactive)
2. Bromine
3. Iodine (least reactive)

So, the ranking is:

• Chlorine: 1
• Bromine: 2
• Iodine: 3
