Uranium

1. Uranium Its used for more than just bombs

2. Martin klaproth & Eugene Peligot Martin klaproth found uranium oxide in 1789 in Germany. He named it after the recently discovered planet Uranus. But the pure element was isolated by Eugene Peligot in 1841. Martin klaproth was very successful in science. Not only did he discover one element but two!! He also discovered Zirconium. Eugene peligot was less successful in science then martin klaproth ,but never the less he still confirmed uraniums existence.

3. Uranium glass Uranium glass was once made into tableware and household items, but fell out of widespread use when the availability of uranium to most industries was sharply curtailed during the cold war in the 1940s to 1990s. Most such objects are now considered antiques or retro-era collectibles. Now modern uranium glass is mainly limited to small objects like beads or marbles as scientific or decorative novelties.

4. Uranium bombs • Uranium bombs make really big explosions. • The picture in the top left is a uranium bomb dropped in water. • The middle picture is a uranium bomb dropped on land. • The last picture is roughly 30% of the Hiroshima bomb. If you can see that 19-meter long airplane in the foreground of the picture (just barely visible) helps put things into perspective. • To explode a uranium bomb, it must have two pieces forced together quickly and in such a geometry that the generation time for fission is extremely short. This leads to an almost instantaneous buildup of the chain reaction, creating a powerful explosion before the pieces can fly apart. Two hemispheres which are explosively forced into contact can produce a bomb such as the one detonated at Hiroshima.

5. Uses for uranium good bad IN-BETWEEN • It is used as a target for X-ray production. • It has been used for centuries to color glass. • It is used as a counterweight for aircraft control surfaces and in the gyroscopes of inertial guidance systems. • Uranium also has a very notorious use which is in the making of atomic bombs. • ammunition for some types of military weaponry

6. Is there uranium in the ocean? Yes there is ,but many people do not realize that seawater has a natural concentration of uranium. The percentage of uranium in seawater is quite low, as you may expect. It has been shown that the uranium concentration of seawater is only about 3 parts per billion, which is about 3 milligrams of uranium per cubic meter. The total volume of the oceans is about 1.37 billion cubic kilometers, so there is a total of about 4.5 billion tons of uranium in seawater. The uranium in the sea water wont affect you because there are only 3 milligrams per cubic meter.

7. Tempature Uranium melts at about 1,132 degrease Celsius. That’s about 2069.6 degrease Fahrenheit. But the boiling point is an amazing 4,131 degrease Celsius. That converted to Fahrenheit is 7,467.8 degrease!!!

8. Essential information Protons, neutrons & electrons Uranium has 92 protons, 146 neutrons and 92 electrons.

9. fun facts about Uranium • Concentration - uranium ranks 48th among the most abundant elements found in natural crustal rock. • Around 33% of the world's uranium is mined in Kazakhstan. • Uranium is not only dangerous because of its radioactivity, but also because it is chemically poisonous to humans. • The element plutonium is made from uranium through a nuclear process. • Uranium is naturally formed in the universe during the supernova of a star. • Uranium is the heaviest of the naturally occurring elements. • Uranium is part of the actinide family. • Uraniums normal phase is a solid.
