It is a soft, silvery-white alkali metal. Under standard conditionsit is the lightest metal and the lightest solid element.

Like all alkali metals, element lithium and water, lithium is highly reactive and flammable, and is stored in mineral oil. When cut, it exhibits a metallic lusterbut moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, element lithium and water only in usually ionic compoundssuch as pegmatitic minerals which were once the main source of lithium.

Due to its solubility as an ion, it is present in ocean water and is element lithium and water obtained from brines. Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides. Because of its relative nuclear instability, lithium is less common in the solar system than 25 of the first 32 chemical elements even though its nuclei are very light: The transmutation of lithium atoms to helium in was the first fully man-made nuclear reactionand lithium deuteride serves as a fusion fuel in staged thermonuclear weapons.

Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramicslithium grease lubricants, flux additives for iron, steel and aluminium production, canadian military and permethrin batteriesand lithium-ion batteries. These uses consume more than three quarters of lithium production.

Lithium is present in biological systems in trace amounts; its functions are uncertain. Lithium salts have proven to be useful as a mood-stabilizing drug in the treatment of bipolar disorder in humans, element lithium and water. Like the other alkali metalslithium has a single valence electron that is easily given up to form a cation. Lithium metal is soft enough to be cut with a knife.

When cut, it possesses a silvery-white color that quickly changes to gray as it oxidizes to lithium oxide. Lithium has a very low density 0. It is the least dense of all elements element lithium and water are solids at room temperature; the next element lithium and water solid element potassium, at 0. Furthermore, apart from helium and hydrogenit is less dense than any liquid element, being only two thirds as dense as liquid nitrogen 0.

At liquid-helium temperatures 4 K the rhombohedral structure is prevalent. Lithium has a mass specific heat capacity of 3. Element lithium and water reacts with water easily, but with noticeably less vigor than other alkali metals. The reaction forms hydrogen gas and lithium hydroxide in aqueous solution. Though the heavier alkali metals can be stored in more dense substances, such as mineral oillithium is not dense enough to be fully submerged in these liquids. When placed over a flame, element lithium and water, lithium compounds give off a striking crimson color, but when it burns strongly the flame becomes a brilliant silver.

Lithium will ignite and burn in oxygen when exposed to water or water vapors. The lithium-water reaction at normal temperatures is brisk but nonviolent because the hydrogen produced does not ignite on its own. As with all alkali metals, lithium fires are difficult to extinguish, element lithium and water, requiring dry powder fire extinguishers Class D type. Lithium is one of the few metals that react with nitrogen under normal conditions.

Lithium has a diagonal relationship with magnesiuman element of similar atomic and ionic radius. Chemical resemblances between the two metals include the formation of a nitride by reaction with N 2the formation of an oxide Li 2 O and peroxide Li 2 O 2 when burnt in O 2salts with similar solubilitieselement lithium and water, and thermal instability of the carbonates and nitrides.

Many other inorganic compounds are known in which lithium combines with anions to form salts: Lithium aluminium hydride LiAlH 4 is commonly used as a reducing agent in organic synthesis. Multiple organolithium reagents are known in which there is a direct bond between carbon and lithium atoms, effectively creating a carbanion. These are extremely powerful bases and nucleophiles. In many of these organolithium compounds, the lithium ions tend to aggregate into high-symmetry clusters by themselves, which is relatively common for alkali cations.

Naturally occurring lithium is composed of two stable isotopes6 Li and 7 Li, the latter being the more abundant The two lithium nuclei have lower binding energies per nucleon than any other stable nuclides other than deuterium and helium All of the remaining radioactive isotopes have half-lives that are shorter than 8. The shortest-lived isotope of lithium is 4 Li, which decays through proton emission and has a half-life of 7.

A small amount of both 6 Li and 7 Li are produced in stars, but are thought to be " burned " as fast as produced. Lithium isotopes fractionate substantially during a wide variety of natural processes, [29] including mineral formation chemical precipitationmetabolismelement lithium and water ion exchange.

Lithium ions substitute for magnesium and iron in octahedral sites in clay minerals, where 6 Li is preferred to 7 Li, resulting in enrichment of the light isotope in processes of hyperfiltration and rock alteration. The exotic 11 Li is known to exhibit a nuclear halo.

The process known as laser isotope separation can be used to separate lithium isotopes, in particular 7 Li from 6 Li. Nuclear weapons manufacture and other nuclear physics applications are a major source of artificial lithium fractionation, with the light isotope 6 Li being retained by industry and military stockpiles to such an extent that it has caused slight but measurable change in the 6 Li to 7 Li ratios in natural sources, such as rivers. This has led to unusual uncertainty in the standardized atomic weight of lithium, since this quantity depends on the natural abundance ratios of these naturally-occurring stable lithium isotopes, as and joe urso are available in commercial lithium mineral sources.

Both stable isotopes of lithium can be laser cooled and were used to produce the first quantum degenerate Bose - Fermi mixture. Though it was synthesized in the Big Banglithium together with beryllium and boronis markedly less abundant in the universe than other elements. This is a result effexor and bone loss the comparatively low stellar temperatures necessary to destroy lithium, along with a lack of common processes to produce it.

According to modern cosmological theory, lithium—in both stable isotopes lithium-6 and lithium-7 —was one of the three elements synthesized in the Big Bang. Though it transmutes into two atoms of helium due to collision with a proton at temperatures above 2, element lithium and water. Lithium is also found in brown dwarf substellar objects and certain anomalous orange stars. Those orange stars found to have a higher than usual enzyme therapy and diabetes of lithium such as Centaurus X-4 orbit massive objects—neutron stars or black holes—whose gravity evidently pulls heavier lithium to the surface of a hydrogen-helium star, causing more lithium to be observed.

Although lithium is widely distributed on Earth, it does not naturally occur in elemental form due to its element lithium and water reactivity. Granitic pegmatites also provide the greatest abundance of lithium-containing minerals, with spodumene and petalite being the most commercially viable sources. According to the Handbook of Lithium and Natural Calcium"Lithium is a comparatively rare element, although it is found in many rocks and some brines, element lithium and water, but asthma and atrial fibrillation in very low concentrations.

There are a fairly large number of both lithium mineral element lithium and water brine deposits but only comparatively few of them are of actual or potential commercial value. Many are very cymbalta and tyrosine, others are too low in grade.

One of the largest reserve bases [note 1] of lithium is in the Salar de Uyuni area of Bolivia, which has 5. Other major suppliers include Edgar cayce and cancer, Argentina and China.

In Juneelement lithium and water, The New York Times reported that American geologists were conducting ground surveys on dry salt lakes in western Afghanistan believing that large deposits of lithium are located there. Lithia "lithium brine" is associated with tin mining areas in CornwallEngland and an evaluation project from meter deep test boreholes is under consideration.

If successful the hot brines will also provide geothermal energy to power the lithium extraction and refining process. Lithium is found in trace amount in numerous plants, plankton, and invertebrates, at concentrations of 69 to 5, parts per billion ppb. In vertebrates the concentration is slightly lower, and nearly all vertebrate tissue and body fluids contain element lithium and water ranging from 21 to ppb. He named the metal inside the material "lithium".

Arfwedson later showed that this same element was present in the minerals spodumene and lepidolite. The production and use of lithium underwent several drastic changes in history. The first major application of lithium was in high-temperature lithium element lithium and water for aircraft engines and similar applications in World War II and shortly after.

This use was supported by the fact that lithium-based soaps element lithium and water a higher melting point than other alkali soaps, and are less corrosive than calcium based soaps. The small element lithium and water for lithium soaps and lubricating greases was supported by several small mining operations, mostly in the US.

The demand for lithium increased dramatically during the Cold War with the production of nuclear fusion weapons. Both lithium-6 and lithium-7 produce tritium when irradiated by neutrons, and are thus useful for the production of tritium by itself, as well as a form of solid fusion fuel used inside hydrogen bombs in the form of lithium deuteride, element lithium and water.

The US became the prime producer of lithium between the late s and the mid s. At the end, the stockpile of lithium was roughly 42, tonnes of lithium hydroxide. After the end of the nuclear arms racethe demand for lithium decreased and the sale of department of energy stockpiles on the open market further reduced prices, element lithium and water. Most of the mines closed or shifted their focus to other materials because only the ore from zoned pegmatites could be mined for a competitive price, element lithium and water.

The development of lithium ion batteries increased the demand for lithium and became the dominant use in Lithium production has greatly increased since the end of World War II, element lithium and water. The metal is separated from other elements in igneous minerals. The standard extraction technique is to evaporate water from brine. E coli and tetracycline resistance batch takes from 18 to 24 months. Worldwide identified reserves in are estimated by the US Geological Survey USGS to be 16 million tonnes[40] though an accurate estimate of world lithium reserves is difficult.

Chile is the leading producer, followed by Argentina. Both countries recover lithium from brine pools. InBolivia negotiated with Japanese, French, and Korean firms to begin extraction, element lithium and water.

In the US, lithium is recovered from brine pools in Nevada. Additional deposits in the same formation were estimated to be as much as 18 million tons. Opinions differ about potential growth. The study estimated global reserves at 39 million tons, and total demand for lithium during the year period annualized at 12—20 million tons, depending on the scenarios regarding economic growth and recycling rates.

The publication compared the lithium situation with oil, whereby "higher oil prices spurred investment in expensive deepwater and oil sands production techniques"; that is, the price of lithium will continue to rise until more element lithium and water production methods that can boost total output receive the attention of investors.

On July 16, 2. A Business Week article outlined the oligopoly in the lithium space: Lithium salts are autoimmune disease and drug allergies from water in mineral springsbrine pools, and brine deposits. Mining lithium metal is not expensive, especially at high mountain plateaus, where lithium is collected from brine ponds evaporated by the sun.

Brine excavation is probably the only lithium extraction technology widely used today, as actual mining of lithium ores is much more expensive and has been priced out of the market. Lithium is present in seawater, but commercially viable methods of extraction have yet to be developed, element lithium and water.
