How did the element get its name?

In 1810, Sir Humphrey Davy named it from Ancient Greek: χλωρóς khlôros (greenish-yellow).

When was it discovered?

Around 1630, chlorine gas was first synthesized in a chemical reaction, however it was not recognized as a fundamentally important substance. Characterization of chlorine gas was made in 1774 by Carl Wilhelm Scheele, who supposed it an oxide of a new element. Finally in 1809 chemists suggested that the gas might be a pure element.

Who discovered the element?

A Swedish Pomeranian pharmaceutical chemist named Carl Wilhelm Scheele was the first to discover chlorine.

What are the properties of this element?

Chlorine is a toxic gas that irritates the skin, the eyes and the respiratory system. It is not found free in nature as it combines readily with nearly all other elements. 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.

What I found unusual about this element

I found it interesting that chlorine is used for producing safe drinking water, even though it is a toxic gas that irritates the skin, the eyes and the respiratory system.
