LITHIUM From the Greek word lithos (stone)

Australian doctor, John Cade, was the first to discover the use of lithium in bipolar disorders. Lithium helps reduce intense mania. It can help and prevent you from bipolar depression. It acts on the central nervous system and can stabilize your mood. Doctors are unsure of how it happens. Lithium is the first effective medication to treat a mental illness.

Properties of LithiumMelting point: 180.5°C (357°F)Boiling point: 1,342°C (2,447°F)Density: 0.535 g/cm3Color: silvery whiteType of Element: alkali metal (includes sodium, potassium, rubidium, cesium, and rancium)

Lithium was dicovered by a Swedish chemist named, Johan August Arfwedson. He discovered lithium in an ore (rock that contains important minerals and elements, as well as metals) from an iron mine, in Sweden. He tried but failed to separate the element from the salt. In 1818, William Thomas Brande and Sir Humphry Davy were successful in isolating the element.

Uses for Lithium

History of Lithium

Lithium is most commonly used in batteries and ceramic/glasses.

Lithium BatteriesLithium batteries are extremely common these days. This is because they are the most energetic rechargeable batteries available. Lithium is a highly reactive element, which means that a lot of energy can be stored in its atomic bonds.It's made of lithium and carbon, both light elements.

Lithium metal burns white, though it gives a crimson color to a flame.

Lithium does not occur free in nature, but it is found in nearly all igneous rocks (above).

Lithium ReactionsWater: Lithium reacts slowly with water to create a colourless solution of lithium hydroxide and hydrogen gas. Air: Lithium metal is easily cut with a knife. This soon tarnishes because of reaction with oxygen and moisture from the air.Halogens: Lithium reacts vigorously with all the halogens to form lithium halides. Acids: Lithium metal dissolves readily in dilute sulphuric acid.

Pure lithium metal is extremely corrosive (harmful) and requires special handling.
