Original sentence: According to current guidelines from IUPAC, the ultimate name for element 117 must end in -ium, not -ine, even if ununseptium turns out to be a halogen
Edited sentence: It should be noted that the ultimate name for element 117 will end in -ium, not -ine, according to guidelines from IUPAC.This is sensible given that the experimental chemistry usually follows the discovery (see ununbium and ununquadium as examples) and that periodic trends possibly begin to break down in this part of the periodic table (see ununquadium)
