Unbipentium is a currently hypothetical chemical element with the atomic number 125.
In the periodic table it is between 124 unbiquadium and 126 unbihexium .
Since there are no natural isotopes of this element , it would have to be generated (synthesized) in an artificial way through nuclear reactions . The name is preliminary and is derived from the ordinal number. Unbipentium is possibly the fifth element to have a g orbital , which would fill the fifth shell with five additional electrons . In the extended periodic table it belongs to the transactinoids ( it is not shown in the "normal" periodic table ).
