What is the number of electrons in a chloride ion? The chemical symbol for Silicon is Si. It is most frequently found as chloride, as in sodium chloride, another name for your everyday table salt. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. The chemical symbol for Holmium is Ho. Hafnium’s large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors.

Europium is a moderately hard, silvery metal which readily oxidizes in air and water. It is a member of the halogen group of elements, appearing between fluorine and bromine moving down the periodic table.
