Facts about the Definition of the Element Chlorine
The Element Chlorine is defined as...
A highly irritating, greenish-yellow gaseous halogen, capable of combining with nearly all other elements, produced principally by electrolysis of sodium chloride and used widely to purify water, as a disinfectant and bleaching agent, and in the manufacture of many important compounds including chloroform and carbon tetrachloride. The most common uses of Chlorine are in Bleaches, Mustard gas, Water purification, Production of chlorates, Paper production, Antiseptic, Insecticides, Paint, Plastics and Medicines.
 

Interesting Facts about the Origin and Meaning of the element name Chlorine
What are the origins of the word Chlorine ?
The name originates from the Greek word 'khloros' meaning green referring to the color of the gas.


 

Facts about the Classification of the Element Chlorine
Chlorine is classified as an element in the 'Halogens' section which can be located in group 7 of the Periodic Table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". The halogens exist, at room temperature, in all three states of matter - Gases such as Fluorine & Chlorine, Solids such as Iodine and Astatine and Liquid as in Bromine.
 

Brief Facts about the Discovery and History of the Element Chlorine
Chlorine was discovered by Carl Wilhelm Scheele in 1774. Chlorine was given its name in 1810 by Humphrey Davy.
 

Occurrence of the element Chlorine in the Atmosphere
Obtained from Earth's oceans salt. Found only as the chloride ion. 1.9% of the mass of seawater is in chloride ions

Facts and Info about the element Chlorine - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Chlorine element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Chlorine was discovered by Carl Wilhelm Scheele in 1774. Chlorine was given its name in 1810 by Humphrey Davy. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Chlorine is just one element that can be found.
