Курсовая работа: Enrico Fermi and his discovery

Содержание

• My work consist of three parts. I start by saying about life Enrico Fermi and his achievement. In the second part I say about Fermi's golden rule. And In the third part I say about discovery of the fermium and its chemical and physical properties.
• To make the conclusion I want to say that Enrico Fermi was the famous and successful scientist. And he made a great contribution in the development of the world science.

• Isotope:
• 17 radioisotopes of fermium have been characterized, with the most stable being 257Fm with a half-life of 100.5 days, 253Fm with a half-life of 3 days, 252Fm with a half-life of 25.39 hours, and 255Fm with a half-life of 20.07 hours. All of the remaining radioactive isotopes have half-lives that are less than 5.4 hours, and the majority of these have half-lives that are less than 3 minutes. This element also has 1 meta state, 250mFm (t½ 1.8 seconds). The isotopes of fermium range in atomic weight from 242.073 amu (242Fm) to 259.101 amu (259Fm).
• Notable characteristics:
• Only small amounts of fermium have ever been produced or isolated. Thus relatively little is known about its chemical properties. Only the (III) oxidation state of the element appears to exist in aqueous solution. Fm and heavier [[isotope]]s can be synthesized by intense neutron bombardment of lighter elements especially uranium and plutonium.
