The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. Element number 118 still has the temporary name ununoctium and it is the final element on the current periodic table.
According to the current rules by IUPAC, the definitive name for ununoctium should end in “-ium”, instead of in “-on” like the other elements in the noble gas group (the first one, helium, is the other exception).
