Uranium is a chemical element with symbol U and atomic number 92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all its isotopes are unstable (with half-lives of the six naturally known isotopes, uranium-233 to uranium-238, varying between 69 years and 4.5 billion years). The most common isotopes of uranium are uranium-238 (which has 146 neutrons and accounts for almost 99.3% of the uranium found in nature) and uranium-235 (which has 143 neutrons, accounting for 0.7% of the element found naturally). Uranium has the second highest atomic weight of the primordially occurring elements, lighter only than plutonium. Its density is about 70% higher than that of lead, but slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite.
How It's Made is a documentary television series that premiered on January 6, 2001 on the Discovery Channel (now known as Discovery Science) in Canada, and Science in the United States. The program is produced in the Canadian province of Quebec by Productions MAJ, Inc. and Productions MAJ 2. In the United Kingdom, it is transmitted on Discovery Channel, Quest, and DMAX.
The show is a documentary showing how common, everyday items (including clothing and accessories like alligator handbags, foodstuffs like bubble gum, industrial products such as engines, musical instruments such as guitars, and sporting goods such as snowboards) are manufactured.
How It's Made is filmed without exploratory text to simplify overdubbing in different languages. For example, the show avoids showing a narrator or host onscreen, does not often have employees of featured companies speak on camera, and keeps human interaction with the manufacturing process to a bare minimum.
An off-screen narrator explains each process, often with humorous puns. Each half-hour show usually has three or four main segments, with each product getting a demonstration of approximately five minutes; exceptions are allowed in the allotted time for more complex products. Usually, every show has at least one product with a historic background note preceding it: Showing how and where the product originated, and what people used before it.

Nuclear technology is constantly in the news. So how exactly do you make nuclear fuel? Special thanks to Life Noggin for animating this video!

In this informational video, I will introduce you to what Uranium is, its properties (both physical and chemical), the history and discovery around it, and its uses in the modern day. The information moves quickly, so make sure to pay attention! This is just a brief explanation as to what Uranium is, there is a lot more information on Uranium on the Internet. Sorry for messing up the audio for the first half of the video, and also for any mess-ups when converting text to speech with my voice.

Uranium! A marvelous and amazing element! Uranium 238 Decay Chain Thorium 234 Protactinium 234m Uranium 234 Thorium 230 Radium 226 Radon 222 Polonium 214 Lead 214 Bismuth 214 Polonium 210 Lead 210 Bismuth 210 Lead 206 (Stable) Radiation and Uranium are amazing and powerful. Like many of natures most powerful creations, Uranium is dangerous and must be treated with respect. Never expose children, pets, or your bare hands to Uranium. If you should ever touch a Uranium sample, always wash your hands carefully. Remember, distance, time, and shielding, and hand washing are your friends. As always, don't try this at home.

Where in the world would you have to go to find Uranium? The best place to look is in a silver mine. Speaking of silver, there's 40 times more uranium than silver. Uranium in mines are in the form of Uraninite (ores). It looks pitch black because it's been oxidized. But what does it looks like when the oxidized layer is taken out? It looks like silver. That is, it's shiny and metallic. Aside form mines, uranium can be found in your back yard, or in sea water. It's just in really small amounts. So small in fact that it's not worth the effort to extract it. All the uranium on earth was formed during the death of a star, it is theorized that most of earth's heat comes from radioactive decay, but it's actually mainly residual heat from earth's creation 4 billion years ago. A larger factor f...
