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 belongs to Group 16 (chalcogens) and Period 7 — a synthetic superheavy element. **Step 2: Apply IUPAC systematic naming rules** For elements with Z > 118 (and those without approved common names), IUPAC uses a systematic approach based on atomic number digits: - **1** = un - **1** = un - **6** = hex - **ium** = suffix **Step 3: Construct the name** Atomic number 116: **1-1-6** → un + un + hex + ium = **Ununhexium** **Step 4: Current IUPAC approval** In 2016, element 116 was officially named **Livermorium (Lv)** after the Lawrence Livermore National Laboratory where it was synthesized. However, before official approval, the systematic IUPAC name was **Ununhexium**. --- **Note:** The answer option C most likely refers to **Ununhexium** (the systematic IUPAC nomenclature name for Z=116 before it received its permanent name). If the question asks specifically about IUPAC nomenclature rules for naming superheavy elements, this systematic approach demonstrates the standardized method used globally.
