Sixth most abundant element in the earth's crust. Burns in air with a brilliant white flame. There are few uses for the pure metal, however its compounds are used in medicine, agriculture and photography. Sodium chloride (NaCl) is table salt. Liquid sodium is sometimes used to cool nuclear reactors. Obtained by electrolysis of melted sodium chloride (salt), borax and cryolite. YvSkXd_VVYk Sodium
Meitnerium was first synthesized in 1982 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt.

The team bombarded a target of bismuth-209 with accelerated nuclei of iron-58 and detected a single atom of the isotope meitnerium-266. Named after Lise Meitner, the Austrian physicist 11 1807 Sir Humphrey Davy England From the English word "soda" (the origin of the symbol Na comes from the Latin word "natrium")
