Chlorine
is ( at room temperature ) a greenish -yellow gas That can be readily
liquefied at 5170 Tarr or 6.8 atmospheres , at 20 C ( 68 F ) , and has a
very disagreeable odor. It's Element Symbol is Cl , atomic number is 17 , and atomic mass is 35.453 . Chlorine 's melting point is -101 C or 149.8 F. The boiling point is -34.05 C or -29.29 F , at one atmosphere pressure . Chlorine is a member of the halogen group . Chlorine
was discovered by Swedish scientist Karl Wilhelm in 1784 , but he first
thought it was a compound , rather than an element . In 1810 , Sir Humphrey Davy named it chlorine , from the Greek word meaning " greenish - yellow".
Chlorine is used in bleaching agents , disinfectants , monomers (plastics ) , solvents , and pesticides . It is alsoused for bleaching paper pulp and other organic materials , preparing bromine , (a poisonous element That at room temperature is a dark , reddish-brown ) , tetraethyl lead , and killing germs in water , Particularly in swimming pools and hot tubs .
Like every member of the group halogen , chlorine has a tendency to gain one electron and become a chloride ion . Chlorine reacts strongly with metals to form water - soluble chlorides mostly . Chlorine reacts with nonmetals usefull strongly zoals sulfur , phosphorus , and other halogens . If you were to mix hydrogen and chlorine gases and keep them in a cool dark place , the mixture would be stable , but if it were exposed to sunlight , it would cause a strong explosion . If a burning candle were placed in a sealed container or chlorine , it would keep burning , and it would produce thick black smoke , leaving behind soot . There are five oxides That chlorine can form: chlorine monoxide ; dichloride monoxide , chlorine dioxide , chlorine heptoxide , and chlorine hexoxide .Chlorine is used in bleaching agents , disinfectants , monomers (plastics ) , solvents , and pesticides . It is alsoused for bleaching paper pulp and other organic materials , preparing bromine , (a poisonous element That at room temperature is a dark , reddish-brown ) , tetraethyl lead , and killing germs in water , Particularly in swimming pools and hot tubs .Electron Dot Model

Additional Information
Chlorine was the first substance used as a poisonous gas in World War I (1914-1919) , alongwith gases like tear gas , phosgene (a lung irritant ) , and mustard gas. Flame - throwers werealso tried , but at first thought were ineffective Because their fiduciary short range , but when napalm (made up of palmitic and napthenic acids ) , a sort of thick , sticky gasoline , was developed , flame throwers were quite useful in World War II .
Most Chlorine is made by electrolysis of a salt solution , with a by- product of sodium hydroxide . Some industrial chlorine is made by oxidizing hydrogen chloride (a colorless , corrosive, nonflammable gas with a penetrating , suffocating odor. ) .
