Discovery Uranium was discovered by Martin Klaproth in 1789 by isolating Uranium inside the mineral Pitchblende. Before this discovery, Martin Klaproth thought that Pitchblende was made of Iron and Zinc, But they found a new element inside of it and named it after the Planet Uranus. But what Martin Klaproth discovered wasn't pure Uranium it was Uranium oxide. Eugene Melchior Peligot produced the first pure Uranium from Uranium oxide in 1841.

Physical Properties of Uranium
- Heavy
- Lustrous
- Softer then steel.
- When it is exposed to air, it gets coated in a layer of oxygen.
- It is also radioactive.
- It isn't hard enough to scratch glass.
- Acids will dissolve Uranium
- Uranium is toxic to consume.

Why is Uranium important?
Uranium is an important element because it is used in the military for atomic bombs, tank armor, and high penetration tank shells. Uranium is used in nuclear reactors. Besides the military and nuclear reactors, it is used as weights for yachts and airplanes. Uranium is also used in smoke detectors and even in dating the age of the earth.

Where is Uranium Used?
- Uranium is used as fuel for nuclear reactors
- In ancient times uranium oxide was used to produce yellow colored glaze and was used to color pottery to kitchen tiles.
- Depleted Uranium is also used for high penetration tank shells and tank armor.
- Depleted Uranium {DU has about 60 percent radioactivety of Natural Uranium} of is used to shield things from radiation
- Used in atomic bombs
- Since it has a long half life it is used to date the age of the earth
- Used in ballasts in yachts and airplanes.
- Used in the chemicals for photography
- The radioisotopes of Uranium is used in smoke detectors.
- It is also used as poison
