Description

Ununseptium is a synthetic element that has not yet been discovered or synthesized. The name ununseptium is used to hold the place in the periodic chart because scientists believe that it exists; it just needs to be synthesized. It is predicted that ununseptium will have chemical traits similar to astatine, and so it is sometimes called eka-astatine. It is predicted to be a dark metallic color, but its appearance is unknown. It is also predicted to be a halogen and a solid.
Isolation
Ununseptium does not exist in nature in any type of form. This element has yet to be synthesized or produced and so isolation procedures are not yet known.

Scientists at the Joint Institute for Nuclear Research in Dubna Russia are planning on an attempt to synthesize ununseptium, but this process has not yet been carried out successfully. Atomic physics must be used to create this element, but it is not yet known which isotopic elements to use as a basis for a reaction resulting in isotopes of ununseptium. Normally, transuranic elements are produced and isolated using heavy bombardment of nuclei or through nuclei fusion; these reactions must be carried out in a nuclear reactor. Most of the products of transuranic synthesis last for mere milliseconds; these products are usually not weighable as only a few atoms can be produced at one time. Ununseptium will probably be no exception. This transuranic element will probably be synthesized using bombardment or fusion techniques, and its isotopic forms that are created will probably last for a very short time before they undergo rapid alpha decay.
