  1. Mitchell Higginbotham Lithium and beryllium

  2. lithium • Atomic number is 3 • Atomic mass is 6.941 • Symbol LI • Number of protons 3 • Number of neutrons 4 • Date of discovery 1817 • Discoverer Johann Arfvedson • Pure form –shiny and black

  3. lithium • Solid • Common • Used to make energizer batteries, pills, and grease. • Makes carbonate pills and is flammable. • Metallic lithium can react with nitrogen oxide, water vapor in the air.

  4. beryllium • Atomic number is 4 • Atomic mass is 9.01218 • Symbol is BE • Number of protons is 4 • Number of neutrons is 5 • Date of discovery 1798 • Discoverer Abbe Rene-Just Hauy.

  5. beryllium • Hard as steel, emerald color, pure form is grey. • Solid • Not common • Used to make gyroscope modules,wrenches,golf clubs, x-ray windows, and thimbles.

  6. compounds • Lithium • Li2SO4 + Na2CO3 → Na2SO4 + Li2CO3 (solid) • Reaction of lithium carbonate with HCl then provides lithium chloride, LiCl. • Li2CO3 + 2HCl → 2LiCl + CO2 +H2O

  7. compounds • Lithium chloride has a high melting point meaning that it should be expensive to melt it in order to carry out the electrolysis.

  8. compounds • Beryllium • Beryllium compounds are very toxic. Its ability to scratch glass is probably due to the formation of a thin layer of the oxide. Aquamarine and emerald are precious forms of the mineral beryllium.

  9. glossary • Vapor=is the gas version of water • Flammable= it is able to cause fire or explosions. • Toxic=which means it is poisonous. • Grey=a mixture of black and white. • Rare= very hard to find or possess.

  10. glossary • Alkaline earth metals=a specific category of the periodic table of elements. • Minerals=are all types of rocks. • Aquamarine=a bluish green color, the color of beryl. • Steel= a very hard type of metal. • Copper=what pennies are made of, a strong metal but still able to bend.
