What Is Uranium?

• Uranium is a dense metal which can be used as an
  abundant source of concentrated energy

3
What is Uranium? (part 1)

• It happens in most rocks in concentrations of 2
  to 4 parts per million and its as common in the
  earths crust as tin,

4
What is Uranium? (part 2)

• tungsten, and molybdenum are.
• It occurs in seawater and could be recovered if
  prices rose significantly.

5
Martin Klaptroth

• Uranium was discovered in 1789 by Martin
  Klaptroth. Klaptroth was a German chemist, in the
  mineral called pitchblende ( the ore where they
  get uranium from). Uranium was named after the
  planet Uranus, which had been discovered eight
  years earlier.

  Actinide series. ( rare earth is made up of 2
  series of elements, Lanthanide and Actinide)

Basic Information

• Number of stable Isotopes there are no stable
  isotopes.
• The isotopes in Uranium are radioactive.

13
The Uses Of Uranium

• a nuclear fuel
• conversion into plutonium in "breeder" reactors
• used in nuclear fuels to generate electrical
  power
• synthesis of isotopes

• nuclear explosive
• used in nuclear fuels to generate electrical
  power
• synthesis of isotopes
• nuclear explosive

14
The Uses Of Uranium

• X-ray targets for production of high-energy
  X-rays
• the nitrate has been used as photographic toner

Radioactive Isotopes of Uranium

• U-230
• U-231
• U-232
• U-233
• U-234

17
Radioactive Isotopes of Uranium

• U-235
• U-236
• U-237
• U-238
• U-239
• U-240

18
U-235

• U-235 is one of the most important isotopes
  because under certain conditions it could be
  split , yielding a lot of energy. So it therefore
  said to be fissile ( could be split,

19
U-235 (contd)

• or divided into the direction of natural joints)
  and we use the expression nuclear fissile. But
  like all radioactive isotopes it also decays.
  Its half-life is 7.0004E8 years.

Thank you!!!!

• First I would like to thank God and my momma
  because, if it wasnt for them this award it
  would not have been possible.
• I also would like to thank my chem teacher Mr.
  Deutch who gave me the opportunity to do this
  presentation.
• And last but not least, to the little people who
  watched this beautiful presentation. LOVE, PEACE
  AND SOUL!!!!!
