Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table.
Answer:
Sodium is represented by symbol Na.
Explanation:
Sodium (Na), a chemical element in the periodic table's alkali metal group (Group 1 [Ia]). Sodium is a very malleable white-silver metal. With 2.8 percent of the Earth's crust, sodium is the sixth most abundant element and the most common alkali metal. It is found in a lot of compounds, especially sodium chloride (NaCl), a common salt that makes the mineral halite and accounts for about 80% of the dissolved components in seawater.
Since sodium is so reactive, it never exists in its free form in the Earth's crust. By electrolyzing fused sodium hydroxide (NaOH), Sir Humphry Davy became the first person to prepare sodium in its elemental form in 1807.Feldspars and micas, two examples of silicate materials, contain significant amounts of sodium. Numerous regions of the globe contain sizable rock salt deposits, and Chile and Peru contain sodium nitrate deposits. The sea has a sodium content of about 1.05 percent, which is equivalent to a concentration of about 3% of sodium halides. In the spectra of stars, including the Sun and the interstellar medium, sodium has been found in both its atomic and ionic forms. Meteorites' silicate content is estimated to be approximately 4.6 sodium atoms for every 100 silicon atoms, according to analysis.
