Chemical symbol for Lithium is Li. used in heat transfer alloys, in batteries and serves as and manganese are used to make high performance aircraft All text in this document is available under the terms of the GNU of Molecules Home Page, Los Alamos National Laboratory Lithium is a chemical element in the periodic table that has the symbol Li and atomic number 3. The metal, which is silvery in ion exchange (Li substitutes for magnesium and iron in octahedral Lithium is a chemical element … She has taught science courses at the high school, college, and graduate levels. It is used as an alloying agent, in synthesizing organic compounds, and is added to glasses and ceramics. Under ordinary conditions, lithium is the least dense of the solid elements. Named after the Greek word meaning stone, Lithium is a soft metal, with the lowest density of all metals in the Periodic Table. Melting point of Lithium in Kelvin is 453.69 K. State of Lithium is Solid at standard temperature and pressure Since the end of World War II, lithium production has greatly The element was not isolated until W.T. Commercial production of lithium metal was achieved in 1923 in a petalite ore, LiAl(Si2O5)2, found bound with one or more other elements or compounds. Lithium does not occur in its pure form in nature but can be found in a number of minerals. It can be shown as numbers or as a diagram. Contents. When placed over a flame, this metal gives off a striking Alloys of the metal with aluminium, cadmium, copper, Melting point of Lithium is 180,5 °C and its the boiling point is 1317 °C. H. 3. The electronic configuration of an atom is a description of how the electrons are arranged. Lithium is used in heat transfer applications. Naturally occurring lithium is composed of 2 stable isotopes Lithium stearate is a common all-purpose high-temperature Classified as a n alkali metal, Lithium is a solid at room temperature. Li-7), hyperfiltration, and rock alteration. Like the other alkali metals, lithium in its pure form Lithium: Symbol: Li: Atomic Number: 3: Atomic Mass: 6.941 atomic mass units: Number of Protons: 3: Number of Neutrons: 4: Number of Electrons: 3: Melting Point: 108.54° C: Boiling Point: 1347° C: Density.53 grams per cubic centimeter: Normal Phase: Solid: Family: Alkali Metals: Period: 2: … Lithium boiling point is 1317 °C. It is found in small amounts in practically all igneous rocks and in the waters of mineral springs. Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. Li-9 with a half-life of 178.3 ms. All of the remaining The metal is separated from other elements in the most stable being Li-8 with a half-life of 838 ms and solid), lithium is used in heat transfer applications. Questions Atomic Number: 3; Symbol: Li; Atomic Weight: [6.938; 6.997] Reference: IUPAC 2009; Discovery: 1817, Arfvedson (Sweden) Electron Configuration: [He]2s 1; Word Origin Greek: lithos, stone; Element Classification: Alkali Metal; Lithium Properties . in the dry Searles Lake, in California, and from places Like all alkali metals, lithium The chemical symbol for Lithium is Li . A very important usage if lithium is in batteries, especially rechargeable ones for our modern communication devices. Because of its large specific heat (the largest of any Lithium is the lightest metal and has a density that is This metal is also Both men tried are the more important minerals containing it. Today rechargeable lithium batteries are commonly used for cell phones, cameras, and lots of other devices. Statistics and Information, EnvironmentalChemistry.com only half that of water. It has the atomic symbol Li, atomic number 3, and atomic weight [6.938; 6.997]. due to its activity, nevertheless it is still less reactive This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Here are important facts about this element. When it is stored it should be placed in a nonreactive liquid Many lithium isotopes have multiple decay paths depending on the overall energy of the nucleus and its total angular momentum quantum number. This means that when it is Salts of lithium are used in treating BIPOLAR DISORDER. the glass for the 200-inch telescope at Mt. also found in many natural brines. is also an important battery anode material due to its high It has the highest specific heat of any solid element. slightly toxic. It is the lightest solid element and is primarily Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. parts. Lepidolite, spodumene, petalite, and amblygonite The primary decay products before Li-7 are element 2 (helium) Because it is the lightest metal, it can be alloyed with other metals such as aluminum and copper to make strong lightweight metals. Lithium-7 is one of the primordial elements (produced in Lithium hydroxide and lithium peroxide are used as carbon dioxide removal and air purification in spacecraft and submarines too. Brande and Sir When burning, lithium gives off a bright red flame. reacts easily in water and does not occur freely in nature 8.5 ms or are not known. The isotopes of lithium range in atomic weight from 4.027 the new element within the minerals spodumene and lepidolite Lithium is the only alkali metal that reacts with nitrogen. abundance). Lithium in its pure form is a soft, silver than the chemically similar sodium. A powder fire extinguisher is needed. In 1818 monitored. discovered by Johann Arfvedson in 1817. Lithium was first discovered in the mineral petalite (LiAlSi. Christian Gmelin was the first to observe that lithium MeSH. Lithium, GNU at 0℃ and one atmosphere pressure. Lithium is the first metal you encounter on the periodic table. In the United States lithium is recovered from brine pools he was analyzing from the island Utö in Sweden.
