sodium basal training: thermonuclear Number: 11  nuclear weight down: 22.98977 figure: Na Electron bod: 1s2 2s2 2p6 3s1 or [Ne] 3s1 Atomic Radius: 190 pm run Point: 97.72 °C (370.87 K, 207.9 °F)  turn Point: 883 °C (1156 K, 1621 °F)  oxidisation State: +1 History/ Etymology: bimetallic alka pains fragment, 1807, coined by English chemist Humphrey Davy from soda; so called because the element was separate from caustic soda ( atomic number 11 hydroxide). The chemical token Na is from natrium, pick name for the element proposed by Berzelius from natron, a name of a type of soda. Sources/ Occurrence: sodium is created in the carbon-burning process by fusing two carbon atoms to plumpher; this requires temperatures above 600 megakelvins and a admirer with at least three solar masses. The Earths crust has 2.6% sodium by weight, making it the sixth near abundant element on Earth. It is found in many an(prenominal) different minerals , whatsoever very soluble, such as  rock salt and natron, others ofttimes less soluble such as amphibole, and zeolite. In the interstellar medium, sodium is identified by the D line; though it has a high vaporization temperature, its abundance allowed it to be spy by Mariner 10 in Mercurys atmosphere.

Properties/ Uses: metallic sodium is employ in the manufacture of sodamide and esters, and in the prep of constituent(a) compounds. The metal also may be used to metamorphose alloys such as aluminum-silicon by improving their mechanistic properties and fluidity. atomic number 11 is used to descale (smooth the surface of) metals and to purify molten metals. Sodium is u sed as a heat interchange agent; for examp! le, liquid sodium is used to cool nuclear reactors. Sodium chloride (table salt, NaCl) is vital for good nutrition. Sodium ions facilitate transmittal of electrical signals in the nervous system and regulate the body of urine balance between body cells and body fluids.
