After years of research and testing, the first nuclear bomb test then occurred in rural New Mexico on July 16, 1945. Robert Oppenheimer, Leo Szilard, Glenn Seaborg, and dozens of others. After the Second World War began, this possibility then became reality with the birth of the Manhattan Project in 1942.īetween laboratories in Los Alamos, NM, Oak Ridge, TN, and Chicago, an international team of scientists began work on the first nuclear weapons. At the end of the 1930s, many envisioned, with both horror and excitement, the possibility of nuclear fission being exploited to create bombs with unparalleled destruction. These findings intrigued many physicists, as they implied that uranium fission could consequently release vast amounts of energy. Just a few years later, in 1939, German physicists Otto Hahn and Fritz Strassman discovered the properties of uranium in performing nuclear fission. However, in 1934, the team working under Italian physicist Enrico Fermi discovered that uranium could emit beta rays. Uranium in WarfareĪfter uranium’s discovery in 1789, the element interested chemists very little for more than a century. However, warfare and energy provide the most famous and impactful uses of uranium. Uranium has many diverse uses in research, particularly for scientists interested in radioactivity and nuclear fission or radioactive dating. Uranium’s Application in Today’s World What is uranium element used for? Additionally, the element has an electronegativity of 1.38 on the Pauling scale. Uranium has an electron configuration of 5f 36d 17s 2. Uranium occupies the fourth element in the Actinide series of the periodic table. It locates in the f-block of the periodic table, with protactinium to its left and neptunium to its right. Uranium has the atomic symbol U with an atomic number of 92. Fine uranium oxide powder is known to spontaneously combust at temperatures of 300☏, posing a serious risk at nuclear power plants, which frequently involve high temperatures.Intriguingly, one kilogram of pure uranium-235 produces 5,184,000 MJ. One kilogram of uranium ore produces 1404 Megajoules of energy, compared to 93 MJ for 1kg of coal. Uranium has a remarkable energetic density from nuclear fission.In 1896, French physicist Henri Becquerel discovered the phenomenon of radioactivity through work with uranium.This heat consequently plays an incredibly important role in plate tectonics. The decay of uranium, as well as thorium and potassium-40, serves as the driving factor behind the heat of the Earth’s mantle.Although known for radioactivity, uranium poses more danger from its toxicity, which can damage organs and cause neurological disorders.This practice was particularly widespread in modern-day Germany and Czechia during the middle ages using pitchblende. ![]() Until the 20th century, humans primarily used uranium in ceramics and glass to add a yellow-green color.Though inactive today, scientists theorize that a species of bacteria could have concentrated uranium-235 because they use uranium as a metabolic catalyst and preferentially select uranium-235. Naturally occurring uranium-fueled fission reactors have been discovered to exist in West Africa, dated to be 2 billion years old.Depleted uranium (free of radioactive isotopes) has some use in dense armor-piercing ammunition.Martin Heinrich Klaproth, the scientist credited with discovering uranium (1789), chose the name in celebration of Uranus’ then-recent discovery (1781). The name “Uranium” comes from the planet Uranus, which itself is named after the Greek god of the sky.Uranium has the highest atomic weight (238.03) and atomic number (92) of any other naturally occurring element on Earth.Because of its radioactivity, uranium has many important uses today, including in electricity generation and military weapons development. Uranium is primarily known for its high atomic weight, as well as its radioactive properties. The element uranium is a dull gray to silvery actinide metal.
