This sodium-39 was the most massive isotope of sodium known to exist. What the physicists in Japan had created was a kind of Frankensodium, an 11-proton particle with a whopping 28 neutrons stuffed into its nucleus. That says nothing about the number of neutrons the particle harbors inside. The periodic table, after all, organizes the elements by the number of protons in their nuclei, and sodium is element number 11. Technically, any nucleus with 11 protons is sodium. Yet those 23 particles do not encompass all that can or could be sodium. Almost all sodium on Earth is sodium-23, where the number refers to the 11 protons and 12 neutrons that make up its nucleus. Don’t let the familiar name fool you you’ll never find this object in ordinary table salt. Then, sifting through the aftermath of the collisions, they found their coveted particle. Using a particle accelerator at Riken, a Japanese research institute, they slammed streams of calcium nuclei against a metal disk, over and over, for hours at a time. A few years ago, a group of physicists created an unusual, never-before-seen subatomic particle. The pure metal is priced at $25 for every 100 gram. The human body contains around 100 grams of sodium.The metal is soft enough to be cut with the edge of a coin.Low sodium foods include frozen lamb, eggs, uncanned dry peas and beans, low sodium peanut butter, etc. Foods high in sodium are canned fish, meat, entrees, beans, salted nuts, etc. Any extra sodium may be harmful and cause high blood pressure and other ailments. An average person intakes 10 grams of salt a day though the recommended daily sodium intake (RDA) is just 3 grams. Human beings usually get the required sodium from their food. Na is essential to all living beings as it is vital for the maintenance of different functions of the body. Sodium vapor used in streetlights gives off a brilliant yellow light. ![]() Sodium carbonate, another sodium salt, is also known as washing soda and is used as a water softener.It also finds application as a feedstock in the chemical industry. Common salt or sodium chloride is added to food to enhance its taste and as a de-icing agent for roads in winter. Its salts have more uses than the metal itself.As a reagent in the chemical industry.As a heat exchanger in nuclear reactors.Lewis Dot Structure for Sodium Sodium Uses If a small piece of Na is dropped into ethanol, it reacts steadily releasing bubbles of hydrogen gas leaving behind a colorless solution of sodium ethoxide. It dissolves readily in dilute sulphuric acid. It reacts vigorously with all the halogens (chlorine, fluorine, etc.) forming sodium halides. During the exothermic reaction, the metal may become so hot that it may catch fire and burn with an orange-colored flame. Sodium reacts rapidly with water to produce a colorless solution of sodium hydroxide (a base) and hydrogen gas. When burnt in air (oxygen), it forms white sodium peroxide and sodium oxide. Besides that, it has 16 synthetic, radioactive isotopes with known half-lives. Naturally occurring Na is its most stable isotope with mass number 23. Sodium (pronunciation SO-dee-em ), represented by the chemical symbol or formula Na, is a soft, malleable element belonging to the family of alkali metals.
