According to IUPAC nomenclature, the name of element having atomic number 116 is — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

# IUPAC Nomenclature for Element 116 **Step 1: Identify the element** Element with atomic number 116 is a synthetic superheavy element in Group 16, Period 7. **Step 2: Apply IUPAC systematic nomenclature rules** For elements with atomic number > 118, IUPAC uses a systematic naming system based on digit-by-digit representation: - 1 = un - 1 = un - 6 = hex **Step 3: Combine digits with phonetic rules** - Atomic number 116 → 1-1-6 - Pronounce as: **un-un-hex** - Apply vowel elision rule (drop final vowel of "un" before vowel "un"): **ununhex** - Add standard suffix **-ium** for elements: **ununhexium** **Step 4: Verify the result** The systematic IUPAC name for element 116 is **Ununhexium** (symbol: **Uuh**) This follows the same nomenclature system used for other superheavy synthetic elements until permanent names are officially adopted by IUPAC. **Answer: C – Ununhexium**
