What is covalency of chlorine atom in second excited state ? — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Carborundum is the common name for silicon carbide (SiC). Step 2: In silicon carbide, each silicon atom is tetrahedrally bonded to four carbon atoms, and each carbon atom is tetrahedrally bonded to four silicon atoms in a giant three-dimensional macromolecular network. Step 3: Because of this continuous network of strong covalent bonds, silicon carbide is classified as a covalent network solid, matching option (b).
