![]() 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. The atomic number of each element increases by one, reading from left to right. Period A horizontal row in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. IsotopesĬhlorine has two isotopes found in nature: Symbol Chlorine 17 35.45 Glossary Group A vertical column in the periodic table. Chlorine gas is highly toxic and was used as a chemical weapon in the First World War. In the past, chlorine was used to make chloroform and carbon tetrachloride (cleaning solvent). It's an oxidising agent and an excellent substitution element. Ĭhlorine is an element with many applications in chemistry. atomic number atomic weight 17 35.453 acid-base properties of higher-valence. Other chlorine compounds are used in the manufacturing process for bullet-proof vests, parachutes, cockpit canopies, and so on. Question: Observe the periodic table information about the element, Chlorine. 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. The atomic number of an element is the number of protons in the nucleus of an atom of that element. ![]() It's used in water, ranging from drinking water to swimming pools. The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. Ĭhlorine is primarily used as a disinfectant. Chlorine liquid at 7.4 bars of pressure in an ampoule and embedded in glass. ![]()
