2. 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)

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

4. 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

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

6. 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.

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

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

9. 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

10. 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

11. 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
