'''Chlorine''' is | '''Chlorine''' is a [[chemical element]] that has the atomic number 17, and the symbol Cl. There is an abundance of chlorine in nature since it is found in common salt as one of the two elements making up sodium chloride. When chlorine is in the form of a gas, its color becomes greenish yellow, and its weight is more than twice that of air. Chlorine gas has a suffocating odor and is very poisonous to every living thing. It is perhaps best known for its powerful disinfecting activity.[http://en.wikipedia.org/wiki/Chlorine] | ||
