These include columbium (Cb), hahnium (Ha), joliotium (Jl), and kurchatovium (Ku), names connected to Christopher Columbus, Otto Hahn, Irne Joliot-Curie, and Igor Kurchatov and also cassiopeium (Cp), a name coming from the constellation Cassiopeia and is hence indirectly connected to the mythological Cassiopeia. Pure sodium may be obtained by electrolysis of molten sodium chloride. Both 22 Na (half-life 2.605 years) and 24 Na (half-life 15 hours) are radioactive cosmogenic isotopes of sodium. It has a fixed atomic mass of 22.98976928 atomic mass unit (u), making it a monoisotopic element. The sole stable isotope of sodium is 23 Na. It reacts vigorously, even violently with water giving off flammable gas. Sodium is a chemical element of the periodic table with chemical symbol Na and atomic number 11 with an atomic weight of 22.9898 u and is classed as a. The element sodium has thirteen different stable isotopes. The origin of the name comes from the Latin word natrium meaning sodium carbonate. Sodium was first commercially produced by thermal reduction of sodium carbonate with carbon at 1,100 degrees Celcius, in the Deville process. Relative atomic mass: 22.989 769 28 (2) Sodium was discovered by Sir Humphry Davy (GB) in 1807.However, the Periodic table generally displays only the symbol of the element and not its entire name. The most common sodium mineral is halite or sodium chloride salt. The periodic table of elements is widely used in the field of Chemistry to look up chemical elements as they are arranged in a manner that displays periodic trends in the chemical properties of the elements.
