Chlorine Liquid chlorine
Chlorine, which at normal conditions is a yellow-green Cl2 gas, is a very caustic substance. Elemental chlorine corrodes nearly every metal and is toxic for every creature. In nature, it always occurs in compounds, the most famous of those is sodium chloride, NaCl, which is table salt. Chloride is a vital part of the body. The compound of hydrogen and chlorine, HCl, dissolved in water, gives hydrochloric acid. Chlorine also is part of the very common plastic PVC.
