What is Untriunium?
'''Untriunium''', also known as element 131 or eka-Einsteinium, is the possible chemical element in the periodic table with the placeholder symbol of Utu and [[atomic number]] 131. Untriunium and Utu are the temporary systematic IUPAC name and symbol, which are used until the element is discovered, confirmed, and a permanent name is decided upon. In the periodic table of the elements, it is expected to follow Untrinilium as the tenth element of the [[Superactinide|Superactinides]] and the twelfth element of the [[Extended periodic table|8th Period]]. Similarly to Untrinilium, it is expected to fall within the range of the [[island of stability]]. ==Related pages== *[[Untrinilium]] *[[Untribium]] [[Category:Hypothetical chemical elements]]
