Uranium.

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 weed of atomic number 92 is 238.0289. Miners called it Pechblende meaning, Pechblende, from the German words pech, which means either pitching or dreary luck, and blende, meaning mineral Uraniums origin easily(p) analysis was done on 1789 by Martin Klaproth, a self-taught well educated german chemist. Klaproth, having extracted from pitchblende what he called a strange manikin of half metal (he had only obscure its oxide), he resisted the temptation to have 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 are solar system at the time, he named it Uran, which in its terminal form became uranium, a name which today is known ecumenic 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 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 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 weak radioactive, decaying slowly that inexorably at the rate! of one milligram per thyroxin per year. It is transformed into inactive lead through a drawstring of radioelements or daughters, each of which has a characteristic anarchy rate, a constant of nature that man has...
