Which element is most chemically similar to chlorine

Bromine

Explanation:

The options to this question are:

A) Sulfur, B) Calcium, C) Oxigen, D) Bromine, E) Argon

The answer is that Bromine is the most chemically similar to chlorine out of the options, because Bromine and Chlorine are halogens.

Halogens are a group of elements: Flourine (F), Chlorine (Cl), Bromine (Br), Iodine (I) and Astatine (At). The elements of this family they all have similar chemical properties.

So since Bromine is the only halogen in the options is the most chemically similar to Chlorine.
