One of the first studies of condensed states of matter was by English chemist Humphry Davy, when he observed that of the forty chemical elements known at the time, twenty-six had metallic properties such as lustre, ductility and high electrical and thermal conductivity.

This was confirmed by Sir Humphry Davy in 1810, who named it chlorine, from the Greek word χλωρος ( chlōros ), meaning " green-yellow.

It was not isolated until 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
