unbitriums
Unbitrium is a hypothetical chemical element with the symbol Ubt and atomic number 123. It has not yet been synthesized and is therefore considered a theoretical element. As part of the extended periodic table beyond element 118, unbitrium would likely fall into a new block of elements, possibly referred to as the g-block, if it were to exist. Its electron configuration would be exceedingly complex, and predicting its chemical properties with certainty is challenging.
The concept of elements beyond the current known range, including unbitrium, is explored within nuclear physics
