Chlorine does not occur in free form in nature. Welcome to "A Visual Interpretation of The Table of Elements", the most striking version of the periodic table on the web. Several salt beds, or ‘lakes’ are found where ancient seas have evaporated, and these can be mined for chloride. This is approximately the sum of the number of protons and neutrons in the nucleus. The percentage of the world reserves located in the country with the largest reserves. History and Uses: Since it combines directly with nearly every element, chlorine is never found free in nature. Promethium chloride was mixed with phosphors that glow yellowy-green or blue when radiation hits them. Each bulk packaging, except a tank car or a multi-unit-tank car tank, must be insulated with an insulating material so that the overall thermal conductance at 15.5 °C (60 °F) is no more than 1.5333 kilojoules per hour per square meter per degree Celsius (0.075 Btu per hour per square foot per degree Fahrenheit) temperature differential. History and Discovery. Chlorine trifluoride appears as a colorless gas or green liquid with a pungent odor. A vertical column in the periodic table. However their use was stopped once it became apparent that when in the atmosphere these compounds absorb ultraviolet light and cause homolytic bond fission producing a chlorine free radical which in turn reacts with ozone. It is categorized as a nonmetal. Chlorine (chemical symbol Cl) is a chemical element. Chlorine is a chemical element with atomic number 17 and element symbol Cl. An element in group 2 has 2 electrons in its outer shell. Chlorine was used during World War I as a choking (pulmonary) agent. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two. A measure of how difficult it is to deform a material. It is a halogen, found in the periodic table in group 17. Humphry Davy investigated it in 1807 and eventually concluded not only that it was a simple substance, but that it was truly an element.
