1. Uranium is an example of an actinoid; also uranium is a solid metal, radioactive, a natural chemical element.
2. Leptons are elementary particles with a very small mass as: electrons, neutrinos and the corresponding antiparticles.
The chemical symbol of uranium is U.

Lepton is the common name given to electron, positron, neutrino, antinuetrino, mu-meson [muon] etc. So an atom has these elementary particles within and come out in specific circumstances.
Uranium does not have a distinct odor. It usually appears as a silvery-white metal in its natural form and can have different colors when it forms compounds. For example, uranium oxide compounds can range in color from yellow to green to black.
Uranium can combine with elements such as oxygen, fluorine, chlorine, and sulfur to form various compounds. For example, uranium dioxide (UO2) is a common compound formed with oxygen, while uranium hexafluoride (UF6) is formed with fluorine.
Leptons are just called that: "leptons". (One example of a lepton is an electron.)

The chemical symbol of uranium is U.
The wavelength of a lepton is inversely proportional to its momentum, which is related to its energy and mass. The spin of a lepton is a fundamental property intrinsic to the particle itself, independent of its momentum or wavelength.

For example, metallic uranium is soluble in nitric acid.
An example: uranium hexafluoride, with the formula UF6.
For example lung cancers, from uranium (and the daughters radium and radon).
All the isotopes of uranium (natural or artificial) are radioactive and unstable.
For example a comparation with plutonium.
That should be the lepton. The electronic lepton (e-) to be accurate. More information: http://en.wikipedia.org/wiki/Lepton
