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.

Facts and Info about
the element Argon - 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.
