Question

chlorine (chemical symbol cl) is located in group 17, period 3. which is chlorine most likely to be? a. a gaseous, highly reactive nonmetal b. a soft, shiny, highly reactive nonmetal c. a metalloid with properties of both metals and nonmetals d. a soft, shiny, highly reactive metal

Explanation:

Chlorine is in Group 17 (halogens) which are non - metals. At room temperature, chlorine is a gas. Halogens are highly reactive. Non - metals are not soft and shiny (those are properties of metals). Metalloids have properties of both metals and non - metals, but chlorine is clearly a non - metal.

Answer:

A. A gaseous, highly reactive nonmetal
