The maximum covalency of the first element in any p-block group (e.g., Boron in Group 13) is restric — p Block Elements Chemistry Question

💡 Solution & Explanation

Elements of the second period (like B, C, N) have only s and p orbitals in their valence shell ($n=2$). Without d-orbitals, they cannot expand their octet, effectively restricting their maximum covalency to 4.
