Chlorine gas was first observed by a Belgian chemist, Jan Baptist van Helmont, in about the year 1630, but the Swedish chemist Carl Wilhelm Scheele is credited with isolating Chlorine as an element in 1774, although he didn't recognize it as an element. That realization came in the early 1800's. Chlorine gas was first used as a weapon on April 22, 1915, at the Battle of Ypres.
For more information, look up "Chlorine" on Wikipedia.
Chlorine was observed for the first time by Jan Baptist van Helmont near 1630 (in Holland) and prepared for the first time in laboratory by Carl Wilhelm Scheele in 1774 (in Sweden), but considered it to be a compound of oxygen.
Sir Humphry Davy (in England) named it after identifying chlorine as a chemical element in 1810.
Chlorine was discovered by Carl Wilhelm Scheele in 1774 when he mistakenly thought it contained oxygen.
Carl Wilhelm Scheele, a chemist from Sweden, isolated the element chlorine in 1774. Chlorine is a gas in its elemental form.
Chlorine was discovered in Sweden by Carl Wilhelm Scheele
Since chlorine is a natural chemical element, it was not invented. It was discovered around 1630.
God invented it when he created the earth. it is a naturally occurring element, therefore not invented by anyone. There is a guy who discovered though, but that's a different question.

Cl is the symbol for chlorine. Watch out when you write chemical symbols that you correctly use upper and lower case! The superscript minus sign tells you that the chlorine has gained an electron and become a chloride ion, negatively charged.
A measurement is the same in milliliters as in grams. One is equal to the other. 150 g of Chlorine Granules are equivalent to 150 ml of Chlorine Granules.
Chlorine is VERY reactive. Many of the compounds formed with chlorine are very dangerous. 2. I recall Asimov claiming that iron would burn (sic) in a chlorine atmosphere. After ignition of some sort I presume. I guess that, since iron(III) chloride is a real compound, that would be evidence that chlorine is reactive with iron. I know that FeCl3 will reacts exothermically in water, so that would sort of be "buring".
It makes a mixture of oxygen and chlorine. There are many compounds between chlorine and oxygen, but they are not made by direct reaction of the elements.
Break point chlorination refers to the continuous addition of chlorine to the water until the chlorine enquiry is met and all present ammonia is oxidized. Once the break point is reached, only free chlorine remains.
Chlorine was discovered earlier.
Chlorine was discovered in Sweden by Karl Scheele in 1774.
Carl Wilhelm Scheele discovered chlorine in 1774. Chlorine wasn't confirmed to be an element until 1810. There is no recorded data of the month and day that it was discovered.
Carl Wilhelm Scheele but it wasn't until 1810 when it was identified as Chlorine by Sir Humphry Davy.
The gas chlorine is a halogen with the chemical symbol Cl; chlorine was discovered by Carl Wilhelm Scheele.
the founder of chlorine is Zack Koebel and it was discovered in 2007
As chlorine was only discovered in the 18th century well lets start with big bang and move on from there!
Chlorine was discovered in 1774 by Carl Wilhelm Scheele, a Swedish chemist
When sodium hypochlorite discovered?
Chlorine has only one type of element and it is the element chlorine with 17 protons, 17 electrons.
it wsnt made it was discovered
