2. Required stuff • Element Symbol- • Element Name-Boron • Atomic number-5 • Atomic Mass-10.81 • Solid liquid or gas? Boron is a natural gas but can be changed into a liquid. • Boron is a metalloid. • Family name- Boron-Aluminum family • Who discovered boron? Joseph-Louis Gay-Lussac and Louis-Jacques • Boron was discovered in 1808. • How is boron used? Boron is used in pyrotechnics and in rockets as ignition fuel.

3. Interesting facts • Boron is the second hardest substance known to man, • Diluted boric acid is used as an eye wash. • Boron holds bones together and keeps them strong. • Boron carbide is very hard and can be used for grinding. In this case, the idea is to pour some of the dark, oily liquid in this can into the oil supply of an engine in order to cause it to grind itself to a halt. I assume the cylinders either become scored to the point that they can't hold compression, or maybe become jammed by the grit. In any case, this is something you would do only under dire circumstances, for example in war (as this can was intended for), or to an ex-girlfriend or something. Not that I'm recommending that, you could get in big trouble. • Silly putty contains about 4% boric acid, which is critically important for its bounce characteristic.

4. Some boron crystal • Londonite-Rhodizite serie ( (Cs K Rb) Al4 Be4 (B Be)12 028 to Rb=0 for the pure Rhodizite cub.), Antandrokomby, Antsirabe`, Madagascar. Yellow, partially translucent crystals on matrix with tourmaline. I repeat these species also for other elements, but are very interesting and rich in rare elements. 3,5x2,5x1,5 cm; 12 g. • Elbaite (Na (Li Al)3 Al6 (BO3)3 Si6 O18 (OH)4 trig.), Minas Gerais, Brazil. Isolated, terminated crystal with rare pink-orange color. • Londonite-Rhodizite serie ( (Cs K Rb) Al4 Be4 (B Be)12 028 to Rb=0 for the pure Rhodizite cub.), Antandrokomby, Antsirabe`, Madagascar. Rich in rubidium example, with Tourmaline (probably Liddicoatite).
