- A.ununennium✓
- B.unnilennium
- C.unununnium
- D.ununoctium
Correct Answer
(A) ununennium
Solution & Explanation
\textbf{Answer:} (A) ununennium \textbf{Solution:} For elements with , IUPAC systematic nomenclature spells out each digit of the atomic number and appends the suffix -ium. For : un, un, enn, giving un-un-enn-ium ununennium (symbol Uue). Distractors: unnilennium corresponds to root (mismatch), unununnium , ununoctium .
