Sodium is a soft, bright, silvery metal which floats on water, decomposing it with the. Group one of the periodic table contains L i superscript plus sign in period 2, N a superscript plus sign in period 3, K superscript plus sign in period 4, R b superscript plus sign in period 5, C s superscript plus sign in period 6, and F r superscript plus sign in period 7. Sodium, like every reactive element, is never found free in nature. Some of the most common are: table salt (NaCl), soda ash (Na 2CO 3), baking soda (NaHCO 3), caustic soda (NaOH), Chile saltpeter (NaNO 3) and borax (Na 2B 4O 7♱0H 2O).Įstimated Crustal Abundance: 2.36×10 4 milligrams per kilogramĮstimated Oceanic Abundance: 1.\): Some elements exhibit a regular pattern of ionic charge when they form ions. Sodium vapor is used in streetlights and produces a brilliant yellow light. Liquid sodium has been used as a coolant for nuclear reactors. ![]() ![]() At room temperature, sodium metal is soft enough that you can cut it with a butter knife. The pure metal is stored in oil or kerosene because it spontaneously ignites in water. On the other hand, certain symbols allude to old element names. Neither element occurs separately and free in nature. Sodium is a silvery-white metal belonging to Group 1 of the Periodic Table, which is the alkali metals group. The symbol is a one- or two-letter abbreviation of the name. Sodium is used in the production of titanium, sodamide, sodium cyanide, sodium peroxide, and sodium hydride. Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). The first lithium mineral petalite, LiAlSi 4 O 10, was discovered on the Swedish island of Utö by the Brazilian, Jozé Bonifácio de Andralda e Silva in the 1790s.It was observed to give an intense crimson flame when thrown onto a fire. This element was first isolated by Sir Humphry Davy in 1807 using caustic soda and. Since sodium can ignite on contact with water, it must be stored in a moisture free environment. The word sodium comes from the English word soda, and its symbol is Na. Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH). Atomic Number Protons, Electrons and Neutrons in Sodium. Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth's crust, it is a very reactive element and is never found free in nature.
