Answer 1

The elements that have properties similar to chlorine (Cl) are F, Br, I. These elements belong to a group called the halogens and have similar chemical properties.

Step-by-step explanation:

The elements that have properties similar to those of chlorine (Cl) are F, Br, I. These elements, along with chlorine, belong to a group called the halogens and have similar chemical properties due to their similar electron configuration. They all have 7 valence electrons, which contributes to their reactivity and ability to form compounds with other elements.
