Sodium is a chemical element; it has symbol Na (from Neo-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. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds.

Sodium is a light-weight, silver-colored metal. Sodium is soft. It can easily be cut with a knife. When someone cuts it, the exposed part will become white over time. It reacts with air to form sodium hydroxide and sodium carbonate. Sodium is a little less dense than water. It floats and reacts instantly with water, producing hydrogen and sodium hy...
These are chemical compounds that contain sodium ions. Sodium only exists in one oxidation state: +1. 1. Sodium aluminum fluoride, used to make aluminum 2. Sodium amide, very strong base 3. Sodium arsenite, colorless solid, very toxic 4. Sodium arsenate, oxidizing agent, very toxic 5. Sodium azide, used in airbags 6. Sodium bicarbonate, baking soda...
Sodium was discovered by Sir Humphrey Davy, an English scientist, in 1807. He created it by electrolyzing sodium hydroxide. Davy named the element after soda, a name for sodium hydroxide or sodium carbonate.
Scientists can use it in the creation of organic compounds. It is used in orange streetlights and lamps that emit ultravioletlight. Sodium compounds are used in soaps, toothpaste, baking, and antacids. The human body needs sodium ions, taken in the form of sodium chloride, to live. Too much of it can cause health problems. Many organisms in the oce...
Sodium does not occur as an element in nature, because it is not stable enough. It exists only in chemical compounds. Sodium ions are found in the ocean and in the Earth's crust. Sodium is normally made by electrolysis of sodium chloride, which is mined from the Earth's crust.

Sodium compounds. Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.
