What is uranium named after?
Uranium was discovered in 1789 by Martin Klaproth, a German chemist, in the mineral called pitchblende. It was named after the planet Uranus, which had been discovered eight years earlier. Uranium was apparently formed in supernovae about 6.6 billion years ago.
How do you find uranium on the periodic table?
Uranium is the 92nd element on the periodic table. It is located in period 7. It is the fourth element of the actinide series that appears below the main body of the periodic table.
Is uranium on the periodic table?
Uranium is a silvery-white metallic chemical element in the periodic table, with atomic number 92. It is assigned the chemical symbol U. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium has the highest atomic weight (19 kg m) of all naturally occurring elements.
