Lithium atomic number7/31/2023 Aluminum-lithium alloys find use in vehicle frames, such as in planes, trains, and automobiles. The most common alloy is the aluminum-lithium alloy, which has numerous industrial applications. Starting in 1949, salts such as lithium carbonate became an active ingredient in treatments for bipolar disorders as well as schizophrenia, with mixed results. Human nutrition does not require lithium as a trace mineral, but it has been used in various pharmaceutical applications over the last 70 years. A typical electron configuration for Li is 1s 22s 1. Its electronegativity reads as 0.98 on the Pauling scale. Like those sibling elements, Li has just one valence electron. It belongs to an elemental family known as alkali metals, which include sodium and potassium. Under hydrogen and after helium, Lithium, with the atomic symbol Li and an atomic number of 3, lies on group 1 of the periodic table. 6Li and 7Li are the two isotopes of lithium.Aluminum products are often cut with lithium to reduce weight.Lithium salts have been found to have a strong antidepressant effect.There are no natural deposits of pure lithium.Lithium is the least dense metal at standard conditions.Lithium is very lightweight, making it useful for vehicle components.In a battery, lithium produces 3+ volts, more than any other metal.7Up soda contained lithium citrate, a mood-stabilizing drug, until 1950.This makes it useful for automobile accessories Grease containing lithium remains thick at high temperatures, whereas other greases become liquid.Lithium reacts with oxygen in the air quickly, becoming dark grey or black.Scissors can cut through this soft element. Many modern technologies use lithium and it has proven pivotal to the development of the 21st-century economy. It is the first metal on the table (excluding the rare metallic hydrogen) and it derives its name from the Greek word “lithos” meaning “stone”. Lithium takes its place as the third element on the periodic table of elements, situated just below hydrogen and to the left of beryllium. Lithium reacts with water, but not as violently as sodium.Įstimated Crustal Abundance: 2.0×10 1 milligrams per kilogramĮstimated Oceanic Abundance: 1.The Element Lithium Introduction to Lithium Lithium carbonate (Li 2CO 3) is used as a drug to treat manic depression disorder. Lithium stearate (LiC 18H 35O 2) is used as a general purpose and high temperature lubricant. Lithium hydroxide (LiOH) is used to remove carbon dioxide from the atmosphere of spacecraft. Lithium is the lightest known metal and can be alloyed with aluminium, copper, manganese, and cadmium to make strong, lightweight metals for aircraft. It is used to make special glasses and ceramics, including the Mount Palomar telescope's 200 inch mirror. Lithium has the highest specific heat of any solid element and is used in heat transfer applications. Many uses have been found for lithium and its compounds. Lithium is not found free in nature and makes up only 0.0007% of the earth's crust. Today, larger amounts of the metal are obtained through the electrolysis of lithium chloride (LiCl). It was first isolated by William Thomas Brande and Sir Humphrey Davy through the electrolysis of lithium oxide (Li 2O). Lithium was discovered in the mineral petalite (LiAl(Si 2O 5) 2) by Johann August Arfvedson in 1817.
