ScenarioBonding determines not just how atoms join, but how the resulting molecules behave in the real world. You are a materials chemist studying buckminsterfullerene (C₆₀) and other carbon allotropes for use in advanced nanomaterials and electronics. Your task is to analyze the bonding, molecular structure, and polarity of these molecules using concepts from Chapter 7. Understanding these properties will help your team design materials with specific mechanical, electrical, or chemical characteristics.Ionic and Covalent Bonding (7.1–7.2):Determine whether the molecule(s) you are studying are held together by ionic, covalent, or a combination of bonds.Explain the relevance of bond type to material stability and conductivity.
