History of Uranium:
Martin Heinrich Klaproth, a German chemist was in an experimental laboratory in Berlin in the year 1789 when he found Uranium. He created a yellow-colored compound by dissolving the pitchblende samples (from the Joachimsal Silver Mines) in nitric acid and neutralized it in Sodium-hydroxide. He then heated it with charcoal, which created a black powder, which he thought was a new element (really was an oxide of Uranium),but this which was what later became Uranium.He then named it Uranium after the planet of Uranus,as well as the god of the sky,named Uranus. After that, studies of Uranium became more frequent and people learned MORE and MORE about Uranium.

Physical Properties:
Uranium is a silver-grey/silvery-grey colored metal with a metallic hue to it. It's very heavy also and can be hard to pick up. It at times can be a powdery-solid that has a dusty feeling. It also has a very high density, which makes it denser than MANY of the other elements. Its shape can range from a circle to really any kind of shape, since you find it naturally. Also, based on if its reformed or in its natural state, the colors may be different from the other kind of Uranium,and there are multiple forms of Uranium,and they all vary.

Refined Uranium about to be used
Civilian Uses:
Even though Uranium is a radioactive element and is dangerous,it still is commonly used. Uranium is used to whiten the coloring in dentures, as a stain/dye in the furniture industry, colored glass in art, and as a power source (nuclear power). As strange as it seems, even though it is a SERIOUS danger, people still use Uranium for things in their average lives.

MILITARY POWER!!!:
Militaries from countries around the world use uranium for advanced weaponry and was to make their army even better.It was originally used as a nuclear material for nuclear bombs,but now,Uranium is used less since there are other good radioactive elements for the bombs. But, they still use Uranium for different kinds of weaponry ammunition, nuclear veichle power sources as substitutes for gas, metal plaiting for vehicles since uranium is a strong metal, gyroscopes for internal guidance systems, and radiation shields. Overall, Uranium is a BIG part of making things for the army.

How A Nuclear Explosion Happens:
The idea of how a nuclear explosion goes off all happended due to neutrons being found out by James Chadswick in the year 1932, and back than, they still weren't sure on what the neutrons could do and what their potential and capabilities were. Than, two years later in the year 1934, Enrico Fermi, a scientist, bombarded and covered the Uranium with loads and loads neutrons, hoping to make a new element that would be higher than Uranium on the Periodic Table, which he would get all the credit for and would make him famous. But while doing this, Enrico found out slow-moving neutrons were more effective and better than the high-energy neutrons while doing the task. Enrico than won a Nobel Prize, and after winning the Nobel prize, he and his wife settled in the United States.
After this information was let out to the world, physicists Otto Hahn, Fritz Strassmann, and Lise Meitner took it up in Germany. They suspected Enrico didn't create a new element, but had split the Uranium atom in two. This back than was a crazy thought and was though to be impossible and unimaginable. But at the time, they were in Germany and Hitler was in control. And since Meitner was a Austrian with Jewish descent, he had to flee. A man than named Niels Bohr got her a job in Stockholm, and Meitner with her nephew named Otto Frisch proved thier suspection was right. Otto Hahn than published the results in January of 1939, and this is what they proved.
When a Uranium atom is cut in half with machinery and technology, each half lets out a a positive force at eachother. And since two forces of the same kind repel eachother away (opposites attract), each half will push the other. And this creates a VERY powerful force, the "explosion". It than goes off, with a VERY heavy and strong impact around it, as well as other effects.
This than was proved to be true, and was started to be used across the world. Three people and a nephew were able to solve one of the science mysteries of the decade at the time with ease, so the after it was published and sent to the public, the United States military started to work on building the first ATOMIC BOMB!

First Uranium Bomb Testing:
This map shows the site where the Trinity Site was, where the first atomic bomb was dropped.
After the information was published to the public eye in Germany about the Uranium atom story with Enrico Fermi, the United States military quickly went into action. Since this was during World War 2 and Germany was Nazi-Party controlled, with the dictator and war criminal Adolf Hitler was in control of Germany, the military reacted as fast as they could and got into action, because they were unsure if the German military AKA Nazis were making a bomb with the split Uranium atoms, and if they were, it would be VERY VERY bad.
The atomic bomb project was VERY big. 12 colleges and universities in the US were studying and researching nuclear bomb making, Uranium, were testing and experimenting, and were gathering the right materials and supplies for making the bomb. By 1942, Enrico Fermi's team of scientists made a sustained chain reaction fission, the first one of its kind. A power plant was built to separate Uranium-235 from Uranium in its natural state, as well as three reactors were built to extract Plutonium from Uranium. In the end, the project cost $2,000,000,000 dollars.
The first atomic bomb was built in Los Alamos, New Mexico, with 200 scientists in 1943. With enough raw materials gathered and with the right supplies, they started to build the bombs. They than designed and made two more bombs, called "Little Boy" and "Fat Man".
On July 13th,1945, at a site called Trinity, which was 100 kilometers from the city Alamogordo,New Mexico. The first atomic bomb was brought to the top of a tall tower, and then dropped down to the ground, and when it hit, it exploded. A intense flash of light blinded people close by and was seen by people in bunkers 10 kilometers away. It also created a GIGANTIC fireball that expanded to 600 meters wide in only 2 seconds. The fireball was more than 12 kilometers high, creating the shape of a large mushroom.This was equal to 18.6 kilotons of TNT, which is the weighted force of 18,600 metric tons. The atomic bomb explosion was 4 times larger than predicted.
Than the Uranium bomb nicknamed "Little Boy" was dropped onto Hiroshima,Japan, as well as a Plutonium bomb nicknamed "Fat Man" was dropped onto Nagasaki,Japan, which caused Japan to surrender and World War 2 to end!
And after that, Uranium and nuclear elements started to be used more frequently, and millitaries in countries across the world started to manufacture, create, and build things such as nuclear bombs and Uranium bombs. This invention would later turn out to be one of the most important advances in military power.

Why It's Important:
Uranium is a important element to have in our lives. Without it, people might not have power, if it's nuclear-powered. Also, then World War 2 might have been won by Germany and Japan and the evil allience, not the USA and their allies. Overall, in history there are many things that would change and become VERY bad if Uranium had not existed, but THANK GOD Uranium was found!
This how the military tests nuclear bombs that use radioactive materials like this bomb in the video. They test it out on fake towns and people that are mannequins to see its effects and if it works. But, it's true in fact that the lead does protect you from radiation. Because lead has a higher density, it blocks the radiation and doesn't let it through at all, like a wall or a shield.

How Touching Uranium with Bare Skin Isn't the End:
Uranium is like metal ore. It's found underground by miners, and brought to us and is refined to be used,but Uranium has its own form of "protection". Uranium emits a radiation, which is VERY dangerous to humans, and has some SERIOUSLY dangerous after effects.
Radiation cause serious nausea, extreme vomiting, lots of aggravating headaches, diarrhea, high temperature fevers, and loss of LOTS of white blood cells. By loosing the white blood cells, which are the main defense for inside your body, it makes you highly vulnerable to diseases. It also causes blood clotting and the production of blood platelets, which make you vulnerable to hemorrhaging. Although this sounds like a horrible way to live,it's better than dying straight away.
Overall, you really never wan't to even touch Uranium really at all in your life AT ALL,unless you want extreme pain.
