Lithium-6 Li - PubChem
WebLe lithium 6 ( 6 Li) est stable et possède un noyau composé de trois protons et de trois neutrons n 1. Il constitue environ 7,5 % du lithium présent dans la nature. C'est un matériau de choix pour la production de tritium, et il peut aussi servir d' absorbeur de neutrons dans des réactions de fusion nucléaire. WebLithium was used during the 19th century to treat gout. Lithium salts such as lithium carbonate (Li2CO3), lithium citrate, and lithium orotate are mood stabilizers. They are used in the treatment of bipolar disorder, since unlike most other mood altering drugs, they counteract both mania and depression. simple tenses worksheet for class 2
Lithium – Wikipedia
Lithium (from Greek: λίθος, romanized: lithos, lit. 'stone') is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosen… WebLithium (from Greek: λίθος, romanized : lithos, lit.
