Uranium properties
Uranium is part of the actinide group. Actinides that have a higher atomic number cannot be found in nature and their life span is shorter. All isotopes of the actinide group, among which uranium is found, are radioactive.
The state of uranium in its natural form is solid. Uranium is a silver-white, metallic-looking chemical element that belongs to the group of actinides. The atomic number of uranium is 92. The chemical symbol for uranium is U. The melting point of uranium is 1405 degrees Kelvin or 1,132.85 degrees Celsius, or degrees Celsius. The boiling point of uranium is 4404 degrees Kelvin or 4131.85 degrees Celsius or degrees Celsius.
Atomic properties of uranium
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. Regarding the position where to find uranium within the periodic table of elements, uranium is in group 3 and period 7. Uranium has an atomic mass of 238.02891 u.
The electron configuration of uranium is [Rn] 5f3 6d1 7s2. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. The mean radius of uranium is 175 pm, its atomic radius or Bohr radius is 156 pm, its covalent radius is 196 ± 7 pm pm, and its Van der Waals radius is 186 pm. Uranium has a total of 92 electrons whose distribution is as follows: In the first shell it has 2 electrons, in the second it has 8 electrons, in its third shell it has 18 electrons, in the fourth, 32 electrons, in the fifth shell it has 21 electrons, in the sixth, 9 electrons and in the seventh it has 2 electrons.
