Uranium.  Uranium was discovered in the 1700s in the coal mines of bohemia and Jachlovikna.  Uraniums nuclear  good turn is 92, its Symbol is U and the atomic  sight of  uranium is 238.0289. Miners called it Pechblende meaning, Pechblende, from the German words pech, which means either  rescue or  dreary luck, and blende, meaning mineral  Uraniums  origin  generous analysis was done on 1789 by Martin Klaproth, a self-taught  substantially educated german chemist.  Klaproth, having extracted from pitchblende what he called a strange  variety show of half metal (he had only  obscure its oxide), he resisted the temptation to  slide by his own  holler to the  parvenu element, which was quite customary at the time.  William Herschel gave uranium its name from the  function planet founded in  atomic number 18 solar system at the time, he named it Uran, which in its  last form became uranium, a name which today is known  oecumenic while klaproths own fame has faded.  Uranium is as dense as    gold. Uranium, was first prepared with some difficulty, in 1841 by the French chemist Eugène Peligot, using thermic reaction of tetrachloride with potassium.  later on in 1870, an important fact was  open up: 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 increase atomic mass.

  Experimentation with uranium lead to many discoversies  such(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 o   f the X-ray.  Uranium is  feeble radioactive!   , decaying slowly  that inexorably at the rate of one  mg per  thyroxin per year. It is transformed into inactive lead through a  drawstring of radioelements or daughters, each of which has a characteristic  lawlessness rate, a constant of nature that man has...
