What is chlorine texture?
Chlorine is a greenish-yellow, diatomic, dense gas with a sharp smell (the smell of bleach). Chlorine occurs in nature mainly as common salt (NaCl), carnallite [ KMgCl2. 6(H20) ], and sylvite (KCl). In its liquid and solid form it is a powerful bleaching, oxidizing and disinfecting agent.
Is chlorine highly reactive?
Halogens are notorious electron-hogs; powerfully attracting electrons from atoms of other elements, particularly from the alkali metals. This makes the halogens highly reactive. Chlorine, being one of the smaller halogens, will react strongly with most elements.
Is chlorine shiny or dull?

What are 2 properties of chlorine?
Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.
Why is chlorine extremely reactive?
Chlorine has the electron configuration [Ne]3s23p5, with the seven electrons in the third and outermost shell acting as its valence electrons. Like all halogens, it is thus one electron short of a full octet, and is hence a strong oxidising agent, reacting with many elements in order to complete its outer shell.
Who gave octave law?
J.A.R. Newlands
Law of octaves, in chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements.
How did the element chlorine get its name?
Scheele thought that chlorine was an oxide of murium, or hydrochloric acid and discovered this greenish, yellow gas. He did not, however, establish chlorine as an element by Humphrey Davy.Chlorine was named after the Greek word “Chloros”, which means pale green.
How does chlorine help in the creation of salts?
Chlorine. Chlorine often combines with metals. While combining with other elements, Chlorine is known to assist in the creation of salts. Chlorine is highly reactive to hydrogen when exposed to the sunlight. Chlorine’s extreme reactivity to various elements easily allows scientists to synthetically reproduce the element.
Who was the first person to discover chlorine?
History:Chlorine was discovered by Karl Wilhelm Scheele, a Swedish chemist, in 1774. Scheele thought that chlorine was an oxide of murium, or hydrochloric acid and discovered this greenish, yellow gas.
Why was chlorine gas replaced in World War 2?
The Chlorine gas was replaced because the reaction between Chlorine abd the conbining elements were more detrimental to the lives of the opposing country’s army. Chlorine is used as a purifier in plastics and polymers, solvents, agrochemicals and pharmaceuticals, as well as other substances.
