Qualitative Analysis and Chemical Bonding

Chemical bonds are like the type of leash used when walking a dog. Ionic, metallic, and network covalent are like walking your dog with a normal leash, it can only go so far and the dog is "held in place". Polar and nonpolar covalent bonds are like walking a dog with a retractable leash. They are still connected to their owner, but the dog can go much further (like the weaker bonds with intermolecular forces).
