What is Lithium as on the Periodic Table? Definition of the Lithium Element
A soft, silvery, highly reactive metallic element that is used as a heat transfer medium, in thermo-nuclear weapons, and in various alloys, ceramics, and optical forms of glass. Lithium reacts with Oxygen to form monoxide and peroxide and reacts easily with Hydrogen at almost 500C (930F) to form lithium hydride. The Atomic Number of this element is 3 and the Element Symbol is Li.

What is Lithium? Origin / Meaning of the name Lithium
Lithium comes from the Greek word lithos which means "stone" because lithium was thought to exist only in minerals at that time.

What is Lithium? Periodic Table Group and Classification of the Lithium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Lithium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

What is Lithium? Occurrence of the Lithium Element

  • Lithium is widely distributed but does not occur in nature in its free form
  • Forms a minor part of almost all igneous rocks
  • Found in many natural brines

Medical Uses of Lithium - Health and Treatments
Interesting information on the Medical Uses of Lithium, Health and Treatments. Lithium carbonate is a psychotropic drug used to treat recurrent attacks of manic-depressive illnesses and has helped correct sleep disorders in manic patients, apparently by suppressing the rapid eye movement phases of sleep. Therapeutic concentrations of lithium have no observable psychotropic effects on normal individuals.

Facts about the History of the Discovery of Lithium Element
Lithium was discovered by Johann Arfvedson in 1817 when he was analyzing minerals from the island of Uto in Sweden. The element was isolated by W.T. Brande and Sir Humphry Davy.

Sir Humphry Davy
Sir Humphry Davy (1778-1829) isolated Sodium, lithium, Potassium, barium, strontium, and Calcium by means of electrolysis. Davy also demonstrated the elementary nature of Chlorine, invented the safety lamp and discovered the stupefying effects of nitrous oxide.
