To understand why carbon is an insulator while silicon is a semiconductor, we need to analyze their electronic configurations and the implications of their atomic structure. ### Step 1: Write the Electronic Configurations - **Carbon (C)**: The electronic configuration of carbon is \( 1s^2 \, 2s^2 \, 2p^2 \). - **Silicon (Si)**: The electronic configuration of silicon is \( 1s^2 \, 2s^2 \, 2p^6 \, 3s^2 \, 3p^2 \). ### Step 2: Identify the Valence Electrons - Both carbon and silicon have 4 valence electrons (2 from the s-orbital and 2 from the p-orbital). ...
