What is special about uranium?
This radioactive metal is unique in that one of its isotopes, uranium-235, is the only naturally occurring isotope capable of sustaining a nuclear fission reaction. (An isotope is a version of the element with a differing number of neutrons in its nucleus.)
Why is uranium-235 important?
Uranium “enriched” into U-235 concentrations can be used as fuel for nuclear power plants and the nuclear reactors that run naval ships and submarines. It also can be used in nuclear weapons.
Can you touch uranium-235?
From a chemical point of view, uranium is a heavy metal and about as toxic as lead. Touching it won’t really do anything to you. Ingesting or inhaling it would be bad, but as long as you don’t have any cuts on your hands and wash them when you’re done you’re unlikely to have any problems.
How long will uranium-235 last?
Uranium abundance: At the current rate of uranium consumption with conventional reactors, the world supply of viable uranium, which is the most common nuclear fuel, will last for 80 years. Scaling consumption up to 15 TW, the viable uranium supply will last for less than 5 years.
What are 3 interesting facts about uranium?
11 Uranium Facts
- Pure uranium is a silvery-white metal.
- The atomic number of uranium is 92, meaning uranium atoms have 92 protons and usually 92 electrons.
- Because uranium is radioactive and always decaying, radium is always found with uranium ores.
- Uranium is slightly paramagnetic.
Who discovered uranium-235?
Arthur Jeffrey Dempster
Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster….Uranium-235.

What type of radiation does uranium-235 emit?
Both uranium and depleted uranium, and their immediate decay products, emit alpha and beta particles and a small amount of gamma radiation. Depletion of U-235 during processing leaves DU appreciably less radioactive than naturally occurring isotopic mixtures.
What does uranium smell like?
Uranium is a metal that has no smell or taste. Uranium is naturally present in bedrock in many places throughout CT.
