Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature - only as a compound. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate).
The boiling point at standard pressure is around â34 ËC, but it liquefies at room temperature at 740 kPa (107 psi). Elemental chlorine is yellow-green, but the chloride ion, in common with other halide ions, has no color in either minerals or solutions (example, table salt).
