Etymology
The name chlorine derives from the Greek word 'chloros', meaning 'green', which refers to its greenish color in the gaseous state. Chlorine was first discovered in 1774 by Swedish chemist Carl Wilhelm Scheele, who initially thought it was a compound instead of an element. It was later identified as an element by Sir Humphry Davy in 1810. The use of chlorine expanded rapidly in the 19th century with its application in water treatment, photography, and the manufacturing of various chemicals, including pesticides and solvents. Chlorine's role in public health, particularly in water sanitation, has made it a critical component in preventing the spread of waterborne diseases.
