Electron Configuration
Isotopes are Element atoms with the same number of protons and electrons as an element but with different numbers of neutrons.
The three naturally occurring isotopes of Uranium are Uranium 234, Uranium 235, Uranium 238.
Uranium is in its' solid state at room temperature.(32ºF)
Uranium is Silverish metal.
Basic Information
Uranium was discovered in 1789 by Martin Klarproth
Uranium was named for the planet Uranus, which is named after one of the first Greek gods.
Uranium was named for the planet Uranus, which is named after one of the first Greek gods.
Uranium is highly radioactive, which means it emits electromagnetic waves at a subatomic level.
Beings that are exposed to radiation can contract Cancer or other harmful mutations.
Extensive research on the radioactivity of Uranium ore was conducted by Marie Sklodowska Curie, after radiation was discovered by Antoine Henri in 1896
Uranium ore can be mined in three ways; Open pit mining, Underground mining, and ISR mining.
Open pit mining is a mining process which removes the top layers of rock and extracting the ore. Open pit mining can only mine low concentrations of Uranium because the higher concentrations are deeper in the earth. Open pit mining leaves a huge eco-footprint.
Underground mining is a method of mining that uses mine shafts and to place explosives that blast out the ore. Underground mining is dangerous and contamination is a problem.
The third way, ISR, is a complex, but safe way to mine Uranium ore and is usually regarded as the most ecologically friendly, but the most expensive.
Uranium is practically impossible to purify. It is a very rare process.
Uranium breaks down into a different element if left alone. In rare cases, the Uranium collides as it breaks apart and forms Plutonium.
Uranium turns yellow under an ultraviolet light.
