electricity. Bismuth has a high resistance to electricity‚ which is unusual for a metal. Ductility- When a solid material stretches or breaks under tensile stress. Natural occurring and man made Bismuth have a very low ductility. The hardness of Bismuth is 2-2.5. Bismuth has 33 isotopes with mass numbers from 185 to 217. Bismuth-209 is the only stable isotope‚ even with the natural radioactivity. Since Bismuth is slightly radioactive it has a slow rate of Alpha particle decay. Alpha Particle Decay is a type

When it comes to organic chemistry and the synthesis of specific products there is an abundant amount of routes that can be taken and still get you the same result. For the following experiment‚ the main focus is the use of a cycloaddition reaction‚ also known as Diels-Alder. According to the lab manual‚ this reaction consists of the addition of a diene and a dienophile and that the Diels-Alder reaction builds stereospecific ring compounds with ease (Weldegirma 80). The reaction takes place between
