Transcript of Chlorine

Chlorine This is a Picture of chlorine It's located Group 17 It's Nucleous has 17 Protons & 18 Neutrons Heres a picture of a chlorine atom it's atomic number is 17 it's atomic mass is 35.45 It's chemical symbol is Cl It's a gas It's a nonmetal Sources Clorine has two isotopes Cl-35 Cl-37 Here's a picture some chips of
calcium carbide in a cylinder of
chlorine It was discovered by Carl Wilhelm Scheele,
but it wasn't until 1810 when it was was identified
as chlorine by Sir Humphry Davy http://en.wikipedia.org/wiki/Chlorine http://www.ptable.com/ http://ezinearticles.com/?What-is-Chlorine-and-What-is-It-Used-for?&id=417625 What it's used for Chlorine has been used to disinfect pools for over one hundred years. Chlorine is used in almost all pools that are open to the public. In addition, most private pool owners, as well as many spa owners, use chlorine in order to keep their pool water clean and safe Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints Facts Since it combines directly with nearly every element, chlorine is never found free in nature. Liquid chlorine burns the skin and gaseous chlorine irritates the mucus membranes Chlorine reacts with nearly all of the elements.
Chlorine compounds are used as bleaching agents by the textile and paper industries.In addittion,chlorine is diatomic and thus forms molecules.It is the only acidic gas with a pale green color.It turns damp blue litmus red and bleaches it white.Chlorine is an oxidising agent and very poisonous.it is used in the purification of water. The vapor density of chlorine = 35.5, which is nearly 2.5 times denser than air (Vapor density of air = 14.4). Chlorine is only moderately soluble in water. A 100 ml of water can dissolve about 46 ml of chlorine at 0oC. The solution smells of chlorine, and is called 'Chlorine water' Chemical Propeties Physical Properties It has 17 electrons Thanks for Watching!! By: Kit Krebsbach
