Lithium Lithium comes from the Greek word for stone, “lithos” Symbol – Li Atomic Number – 3 Atomic Mass – 6.941 Category – Alkali metal Its density is half of water’s (.5 grams per cubic cm)

Periodic Table of Elements Lithium Lithium is located in Period 2, Group 1.

Lithium Solid at room temperature Melting point-180.5 degrees Celsius Boiling point-1342 degrees Celsius Not found in pure form in nature, it can be found in compounds normally in almost all igneous rocks and brines Lithium is a metal

Who discovered Lithium? Johann August Arfvedson Discovered in 1817 Isolated by William Thomas Brande +Sir Humphrey Davis Was discovered in Stockholm, Sweden

Bohr Model of LITHIUM Description: Crimson to flame, white to strong flames, soft silvery – white, light, has a metallic smell to it, and is 0.6 on Moh’s scale. Lithium is toxic and targets the central nervous system.

Lewis Dot Structure for LITHIUM Because Lithium is in Group 1, it only has one valence electron

Lithium Uses Alloying agent Battery anode material (in pacemaker batteries) Special glasses and ceramics Heat transfer applications Lubricants

Lithium Uses (Cont.) Lithium carbonate-is used in a drug to treat maniac depression disorder Lithium hydroxide-is used to remove carbonate from the atmosphere/spacecraft

How Lithium Bonds Lithium usually forms ionic bonds When lithium bonds, it loses one electron, so the other element gains an electron Lithium is highly reactive

Fun Facts Is $300/pound Is the lightest of all metals with the density of about half of water Can be discovered in California in Searles Lake and Nevada Has the highest specific heat of all solid elements
