Uranium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.

Uranium in its depleted and unenriched forms has numerous commercial applications due to its great density and its bright yellow-green color in glass and ceramics. Its great density has found military applications in armor piercing armaments and in protective shielding. It is added to ceramic frits, glazes and to color bar for glass production because of its bright yellow shade. Uranyl Nitrate and Uranyl Acetate are used in medical and analytical laboratories. The name Uranium originates from the planet Uranus.

Uranium is a Block F, Group 3, Period 7 element. The number of electrons in each of Uranium's shells is 2, 8, 18, 32, 21, 9, 2 and its electronic configuration is [Rn] 5f³ 6d¹ 7s². In its elemental form uranium's CAS number is 7440-61-1. The uranium atom has a radius of 138.5.pm and it's Van der Waals radius is 186.pm. Uranium is harmfulboth through its radioactivity and chemical toxicity.

Uranium was discovered by Martin Heinrich Klaproth.

Abundance. The following table shows the abundance of uranium and each of its naturally occurring isotopes on Earth along with the atomic mass for each isotope.

The following table shows the abundance of Uranium present in the human body and in the universe scaled to parts per billion (ppb) by weight and by atom:

Safety Data and Biological Role. The safety data for Uranium metal, nanoparticles and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the left margin. Uranium compounds have no biological role.

Ionization Energy. The ionization energy for uranium (the least required energy to release a single electron from the atom in it's ground state in the gas phase) is stated in the following table:

Conductivity. As to uranium's electrical and thermal conductivity, the electrical conductivity measured in terms of electrical resistivity (0 °C) 0.280 µΩ·m and its electronegativities (or its ability to draw electrons relative to other elements) is 1.38. The thermal conductivity of radium is 27.5 W m^-1 K^-1.

Thermal Properties. The melting point and boiling point for uranium are stated below. The following chart sets forth the heat of fusion, heat of vaporization and heat of atomization.
