Na element group12/31/2023 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. Sodium vapor is used in streetlights and produces a brilliant yellow light. Liquid sodium has been used as a coolant for nuclear reactors. Sodium is used in the production of titanium, sodamide, sodium cyanide, sodium peroxide, and sodium hydride. Since sodium can ignite on contact with water, it must be stored in a moisture free environment. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH). Salt overdose is possible, in 2013, doctors reported on the case of a 19-year-old man who went into a coma after chugging a bottle of soy sauce.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.Sodium metal doesn’t burn when it comes in contact with water but produces hydrogen, which gives the impression that the sodium is burning.Sodium is used in fireworks to produce bright yellow sparks. Sodium burns with a bright yellow light.Sodium is an essential part of the human diet and is usually ingested through the compound sodium chloride (common salt), however too much salt in a diet can not only raise an individual's blood pressure but also become poisonous, which could lead to seizures, coma and death. When pure sodium makes contact with water it forms hydrogen, which burns violently and it would therefore probably result in death if swallowed by a human or animal. Pure sodium metal is highly reactive and should never be brought near water or any moist surface (like your mouth for instance) without the proper protection. He found the element by isolating it from caustic soda using electrolysis This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water. Sir Humphry Davy, a British chemist, discovered sodium in 1807. Salt and other sodium-containing compounds have been used long before the discovery of the element sodium. In theory, sodium could be recycled and reused, but there is no economic reason to recycle sodium since it is naturally recycled back into the earth's crust and water. Ordinary seawater contains a high percentage of sodium and there is currently no indication that we will be running out of sodium any time soon. Metallic sodium is priced at about 15 to 20 cents per pound and is the cheapest of the light metals. Sodium is now produced commercially through the electrolysis of molten sodium chloride, based on a process patented in 1924. It is the most abundant of the alkali group of metals and appears in nature as common salt, which forms the mineral halite, which is about 80% of the dissolved constituents in seawater. Sodium is the fourth most abundant element on earth, comprising about 2.6% of the earth's crust. Most likely the second most useful compound is sodium carbonate, also known as washing soda, which is used as a water softener.īaking soda also contains sodium and is used in cooking. The most common sodium compound is sodium chloride, which is normal table salt, used on food and to throw on iced roads. Sodium is also used as a reagent in the chemical industry.īut the uses for sodium compounds are much greater than that of pure sodium metal. Liquid sodium is used as a heat exchanger in nuclear power plants. Pure sodium is used in the production of titanium. Similar to lithium, sodium is usually stored in a closed container in kerosene or mineral oil, to prevent or limit the reaction with oxygen in the air. The elements of group 1 of the periodic table are hydrogen (H(, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs). Sodium is a soft silver-white metal, with a similar appearance to lithium. Pure sodium will cause a violent exothermal reaction when it comes into contact with water. The elements in group 2 (the second column) form. But the element behind these compounds is much less innocent. These elements (except hydrogen) are known as alkali metals, and they all have similar chemical properties. Sodium chloride and sodium bicarbonate are compounds used daily in every household. Sodium is the wonderful metal in common table salt, but did you know it floats on water?
