Lithium (from Ancient Greek: λίθος, líthos, 'stone') is a chemical element; it has symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.

Mar 26, 2025 · Lithium, chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale. Learn more about the occurrence and uses of lithium.

Aug 14, 2023 · Lithium a mood stabilizer that is a used to treat or control the manic episodes of bipolar disorder (manic depression). Manic symptoms include hyperactivity, rushed speech, poor judgment, reduced need for sleep, aggression, and anger. Lithium also helps to prevent or lessen the intensity of manic episodes.

Dilithium, Li 2, is a strongly electrophilic, diatomic molecule comprising two lithium atoms covalently bonded together. Li 2 has been observed in the gas phase. It has a bond order of 1, an internuclear separation of 267.3 pm and a bond energy of 102 kJ/mol or 1.06 eV in each bond. [1] The electron configuration of Li 2 may be written as σ 2 ...

May 19, 2015 · Here are a collection of lithium facts, including its properties, uses, and sources. Basic Lithium Facts. Name: Lithium. Atomic Number: 3. Element Symbol: Li. Group: 1. Period: 2. Block: s. Element Family: Alkali Metal. Electron Configuration: [He]2s 1 (shorthand) or 1s 2 2s 1 (full) Discovery: Johan August Arfwedson in 1817.

Jun 30, 2023 · Lithium is most commonly found combined with aluminum, silicon, and oxygen to form the minerals known as spodumene (LiAl(SiO 3) 2) or petalite/castorite (LiAlSi 4 O 10). These have been found on each of the 6 inhabited continents, but they are mined primarily in Western Australia, China, and Chile.

Due to its narrow therapeutic index, serum levels of lithium exceeding 2 mEq/L are considered toxic, which falls within its therapeutic range. Lithium toxicity can result in interstitial nephritis, arrhythmia, sick sinus syndrome, hypotension, T-wave abnormalities, and bradycardia.

In World War II, lithium was majorly used as greases for the engines of aircrafts. US was the primary producer of lithium between 1960s to mid-1980s. During the Cold War, the production of lithium was increased drastically as it was used in the production of nuclear fusion weapons.

It was first isolated by William Thomas Brande and Sir Humphrey Davy through the electrolysis of lithium oxide (Li 2 O). Today, larger amounts of the metal are obtained through the electrolysis of lithium chloride (LiCl).
