The last compound is a common reducing agent in chemical synthesis. Samarium has no significant biological role but is only slightly toxic. Samarium was discovered in 1879 by the French chemist Paul-Émile Lecoq de Boisbaudran and named after the"
"sodium acetate, and EtOAc for ethyl acetate. The pseudoelement symbol ""Ac"" is also sometimes encountered in chemical formulas as indicating the entire acetate ion (CHCO), or the acetyl group (CHCO). It is not to be confused with the symbol of actinium, the first element of the actinide series; context guides disambiguation. For example, the formula for sodium acetate might be abbreviated as ""NaAc"", rather than ""NaCHO"". Care should also be taken to avoid confusion with peracetic acid when using the OAc abbreviation; for clarity and to avoid errors when translated, HOAc should be avoided in literature mentioning both compounds. Although"

"Scandium Scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare-earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide. Because of the low availability and the difficulties in the preparation of metallic scandium, which was first done in 1937, applications for scandium were not"
"""Sb"" (stibium) for antimony. Chemical symbols are understood internationally when element names might require translation. There have sometimes been differences in the past. For example, Germans in the past have used ""J"" (for the alternate name Jod) for iodine, but now use ""I"" and ""Iod"". The first letter of a chemical symbol is always capitalized, as in the preceding examples, and the subsequent letters, if any, are always lower case (small letters). Thus, the symbols for californium and einsteinium are Cf and Es. There are also symbols in chemical equations for groups of chemical elements, for example in comparative formulas."
"by Jöns Jakob Berzelius in his system of atomic symbols, and is an abbreviation of the element's New Latin name ""natrium"", which refers to the Egyptian ""natron"", a natural mineral salt mainly consisting of hydrated sodium carbonate. Natron historically had several important industrial and household uses, later eclipsed by other sodium compounds. Sodium imparts an intense yellow color to flames. As early as 1860, Kirchhoff and Bunsen noted the high sensitivity of a sodium flame test, and stated in Annalen der Physik und Chemie: In a corner of our 60 m room farthest away from the apparatus, we exploded 3"
"Neodymium Neodymium is a chemical element with symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a rare earth, it is a fairly common element, no rarer than cobalt, nickel, or copper, and is widely distributed in the Earth's crust. Most"

The decahydrate of sodium sulfate is known as Glauber's salt after the Dutch/German chemist and apothecary Johann Rudolf Glauber (1604–1670),"
"Latin name of ""sodanum"" was used as a headache remedy. The name sodium is thought to originate from the Arabic ""suda"", meaning headache, as the headache-alleviating properties of sodium carbonate or soda were well known in early times. Although sodium, sometimes called ""soda"", had long been recognized in compounds, the metal itself was not isolated until 1807 by Sir Humphry Davy through the electrolysis of sodium hydroxide. In 1809, the German physicist and chemist Ludwig Wilhelm Gilbert proposed the names ""Natronium"" for Humphry Davy's ""sodium"" and ""Kalium"" for Davy's ""potassium"". The chemical abbreviation for sodium was first published in 1814"

"Sodium hydride Sodium hydride is the chemical compound with the empirical formula NaH. This alkali metal hydride is primarily used as a strong, yet combustible base in organic synthesis. NaH is representative of the saline hydrides, meaning it is a salt-like hydride, composed of Na and H ions, in contrast to the more molecular hydrides such as borane, methane, ammonia and water. It is an ionic material that is insoluble in organic solvents (although soluble in molten Na), consistent with the fact that H remains an unknown anion in solution. Because of the insolubility of NaH, all reactions involving NaH"
"Holmium Holmium is a chemical element with symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare-earth element. Holmium was discovered by Swedish chemist Per Theodor Cleve. Its oxide was first isolated from rare-earth ores in 1878. The element's name comes from ""Holmia"", the Latin name for the city of Stockholm. Elemental holmium is a relatively soft and malleable silvery-white metal. It is too reactive to be found uncombined in nature, but when isolated, is relatively stable in dry air at room temperature. However, it reacts with water and corrodes readily and also burns in"
"sodium carbonate decahydrate (hydrated soda ash) that makes up most of the historical salt. The English and German word ""natron"" is a French cognate derived from the Spanish ""natrón"" through Latin ""natrium"" and Greek νίτρον ""nitron"". This derives from the Ancient Egyptian word ""nṯry"" 'natron'. ""Natron"" refers to Wadi El Natrun or Natron Valley in Egypt, from which natron was mined by the ancient Egyptians for use in burial rites. The modern chemical symbol for sodium, Na, is an abbreviation of that element's New Latin name ""natrium"", which was derived from ""natron"". Historical natron was harvested directly as a salt"
"Vanadium Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silvery-grey, ductile, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by analyzing a new lead-bearing mineral he called ""brown lead"", and presumed its qualities were due to the presence of a new element, which he named ""erythronium"" (derived from Greek for ""red"") since, upon heating, most of the salts"
