The strongest of all atomic bonds are...

• A. Ionic
• B. Covalent
• C. Metallic
• D. Hydrogen

Answer: (B)

Bond energy determines how strong a bond is. Covalent bonds, where atoms share electrons, create very strong attractions because the shared electron density pulls the nuclei together tightly. In networks like diamond, each carbon forms four robust covalent bonds in a rigid 3D lattice, giving exceptional hardness and a very high melting point—clear evidence of how strong covalent bonds can be. While ionic bonds can be strong in a solid lattice due to electrostatic forces, and metallic bonds hold metals together well as a whole, the strength per bond in typical covalent connections—especially in network solids—generally surpasses the others listed. Hydrogen bonds are weaker because they are intermolecular attractions, not true covalent bonds. So, the strongest type of bonding here is covalent.
