This is a group of related tests. Its only stable isotope is 23Na. In 1807 Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide (NaOH). For each compound, a formal oxidation number for sodium is given, but the usefulness of this number is limited for p-block elements in particular. Sodium is an alkali metal, being in group 1 of the periodic table. Characteristics and Properties Sodium in its pure form is very reactive. Sodium chloride or salt (NaCl) Soda ash (Na 2 CO 3) Baking soda (NaHCO 3) Sodium hydroxide or caustic soda (NaOH) Sodium nitrate or Chilean saltpeter (NaNO 3) Sodium Borate or borax (Na 2 B 4 O 7) Interesting facts: It is found free in nature. Sodium chloride is common table salt which is important in animal nutrition. Sodium carbonate is also used to make a very large number of commercial products, such as glass, pulp and paper, soaps and detergents, and textiles. Wikipedia Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. Light (for sodium-reduced products) – If the food is “low calorie” and “low fat” and sodium is reduced by at least 50 percent per serving; Light in sodium – If sodium is reduced by at least 50 percent per serving; Remember: Sodium levels vary in the … Sodium is an important constituent of a number of silicate materials, such as feldspars and micas. It is abundant in the sun and other stars. Sodium bicarbonate (NaHCO3). It is placed in group 1 of periodic table as it has a single electron in its outer most shell that it readily donates, creating a positively charged ion, the Na+ cation. Properties and production. At room temperature Sodium is soft, silvery-white metal which can be easily cut with a knife. The general valence electronic configuration of group 1 elements is {eq}{\text{n}}{{\text{s}}^{\text{1}}}. When sodium bicarbonate is dissolved in water, it produces a fizzing reaction. That reaction can be … Sodium has an atomic number of 1 and atomic mass of 22.98. It is a soft, silvery-white, highly reactive metal. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. Because sodium is extremely reactive, it never occurs in the free state in Earth’s crust. It is highly reactive. Sodium is an alkali metal located in the first group or column of the periodic table. The sodium atom has 11 electrons and 11 protons with one valence electron in the outer shell. It will ignite spontaneously on water. Other important forms of sodium are soda ash(Na2CO3), baking soda (NaHCO 3), Chili saltpeter (NaNO 3) which is sodium nitrate. The sodium blood test is often part of a basic metabolic panel. Sodium Page One. in nature sodium is fount in soda niter, cryolite, amphibole and zeolite. Sodium Menu. Atomic Number – Protons, Electrons and Neutrons in Sodium. Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Sodium. The group number of sodium is 1. A sodium blood test (also called a serum sodium test) is a way for your health care provider to measure the amount of sodium in your blood. It will float on water. The basic metabolic panel includes tests for:
