![]() ![]() They have created a complete suite of short videos on every element on the periodic table of elements. The video below is from the University of Nottingham's periodic videos project. IsotopesĬhlorine has two isotopes found in nature: Symbol Chlorine properties, uses and trends Periodic Table of the Elements - complete information about the Chlorine element - Facts, atomic mass, melting point, How to Locate on Periodic Table, History, Abundance, Physical Properties, Thermal Properties, Crystal Structure, Atomic & Orbital Properties, electron configuration, Chemical Properties Chlo. of (mass chlorine The element 34.97 atoms amu) chlorine are and chlorine-35. Chlorine gas is highly toxic and was used as a chemical weapon in the First World War. 2.52.5 PERIODIC TABLE PERIODIC TABLE The atomic weight of an element is. The nucleus is composed of protons and neutrons. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. In the past, chlorine was used to make chloroform and carbon tetrachloride (cleaning solvent). Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure. ![]() As a result, this chart actually displays the mass number of a specific isotope for each element. These five toxic, non-metallic elements make up group 17 and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (As). The Periodic Table of Elements C 6 CARBON 12 Atomic Number Chemical Symbol Atomic Weight Chemical Name. It's an oxidising agent and an excellent substitution element. The halogens are located in group 17 (formally known as group VIIA) on the left of the noble gases on the periodic table. Historically: Chlorine was first used as a germicide in the maternity wards of Vienna General Hospital in Austria in 1847 and became one of humanitys fiercest. Ĭhlorine is an element with many applications in chemistry. Other chlorine compounds are used in the manufacturing process for bullet-proof vests, parachutes, cockpit canopies, and so on. Chlorine is also a component of polyvinyl chloride (PVC) plastic which is used for things like window frames, car interiors, electrical wiring insulation, and water pipes. It's used in almost every product that requires disinfecting at some stage of its production. ![]() It's used in water, ranging from drinking water to swimming pools. Ĭhlorine is primarily used as a disinfectant. Chlorine liquid at 7.4 bars of pressure in an ampoule and embedded in glass. Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure. ![]()
