Mitchell Higginbotham Lithium and beryllium

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

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.

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

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.

compounds Lithium Li 2 SO 4 + Na 2 CO 3 → Na 2 SO 4 + Li 2 CO 3 (solid) Reaction of lithium carbonate with HCl then provides lithium chloride, LiCl. Li 2 CO 3 + 2HCl → 2LiCl + CO 2 +H 2 O

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

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. compounds
