Uranium is the metal of the actinide series of the periodic table.
The symbol of uranium is ‘U’ and atomic number is ’92.’
In 1789, Martin Heinrich Klaproth had discovered the element uranium and named it after the name of Uranus.
Uranium is a silvery-white metal.
A uranium atom has 92 electrons as well as 92 protons, of which 6 are valence electrons.
Because of having unstable isotopes, uranium is a weak radioactive element.
Uranium-238 is the most common isotope of uranium.
Uranium occurs naturally in very low concentrations i.e. a few parts per million in rock, soil, and water.
Uranium decays gradually (slowly) by emitting its alpha particle.
Uranium has poor electric conductivity (so poor conductor of electricity).
Uranium is malleable, ductile, and marginally paramagnetic
Uranium is (naturally) found as uranium-238, uranium-235, and uranium-234.
The half-life of uranium-238 is about 4.47 billion years almost the age of the Earth and the half-life of uranium-235 is about 704 million years.
