Covalent vs Ionic Compounds: Key Differences

The video tutorial explains the formation and properties of covalent and ionic compounds. Covalent compounds form when non-metals share electrons, resulting in neutral molecules. They tend to be soft, have low melting and boiling points, and are poor conductors of electricity. Ionic compounds consist of cations and anions, forming strong bonds that create solid crystals with high melting points. They are good conductors when dissolved in solutions. The video concludes with a reminder to practice kindness.
