Uranium.

Uranium. Uranium was discovered in the 1700s in the coal mines of bohemia and Jachlovikna. Uraniums atomic come is 92, its Symbol is U and the atomic mass of atomic number 92 is 238.0289. Miners called it Pechblende meaning, Pechblende, from the German words pech, which means either pitch or deplorable luck, and blende, meaning mineral Uraniums commencement ceremony complete analysis was done on 1789 by Martin Klaproth, a self-taught tumefy educated german apothecary.

Later in 1870, an important fact was establish: uranium is the last and heaviest element present on earth. This was present by Dimitri Mendeleev in his famous perodical classification of the elements by chemical properties and increasing atomic mass.

experimentation with uranium lead to many discoversies much(prenominal) as the X-ray by Wilhelm Röntgen, on November 8, 1895. Wilhelm Röntgen, was awarded the first Nobel prize in 1901 for the development of the X-ray. Uranium is weakl! y radioactive, decaying slowly merely inexorably at the rate of one milligram per triiodothyronine per year. It is change into inactive lead through a stove of radioelements or daughters, each of which has a characteristic disintegration rate, a unvarying of nature that man has...
