Unbihexium, also known as element 126 or eka-plutonium, is a hypothetical chemical element; it has atomic number 126 and placeholder symbol Ubh. Unbihexium and Ubh are the temporary IUPAC name and symbol , respectively, until the element is discovered, confirmed, and a permanent name is decided upon.

When an element is discovered (synthesized), the element will be removed from this category. (That's when period 8 is not the same as "theoretical extension" anymore.) Subcategories

Thus element 164 with 7d 10 9s 0 is noted by Fricke et al. to be analogous to palladium with 4d 10 5s 0, and they consider elements 157–172 to have chemical analogies to groups 3–18 (though they are ambivalent on whether elements 165 and 166 are more like group 1 and 2 elements or more like group 11 and 12 elements, respectively). Thus ...
The facts fall within a hierarchy of evidence. The highest quality evidence is the definitions (e.g. unbihexium is part of the superactinide series by the definition of a superactinide) and confirmed theories (e.g. example, the existence of magic numbers is confirmed).
