The only problem was that those who did so did not recognize the element and did not know it then. Early Detection.

Carl Wilhelm Scheele was the first to study and isolate chlorine gas. He is credited for its discovery in 1774. However, he did not recognize it as an actual element.
Chlorine is a chemical element with symbol Cl and atomic number 17. It also has a relative atomic mass of 35.5. Chlorine is in the halogen group (17) and is the second lightest halogen following fluorine.The element is a yellow-green gas under standard conditions, where it forms diatomic molecules.Chlorine has the highest electron affinity and the third highest electronegativity of all the reactive elements.he most common compound of chlorine, sodium chloride, has been known since ancient times; archaeologists have found evidence that rock salt was used as early as 3000 BC and brine as early as 6000 BC. Around 1630, chlorine was recognized as a gas by the Flemish chemist and physician Jan Baptist van Helmont.
