  • Explain the difference between an ionic bond and a covalent bond, providing an example of each.
    Ionic Bond: Formed between a metal and a non-metal through the transfer of electrons. Covalent Bond: Formed by the sharing of electrons between non-metal atoms.
    Example covalent: Water (H2O)
    Example ionic: Sodium Chloride (NaCl)
  • Ionic compounds tend to have high melting and boiling points, conduct electricity when dissolved in water or molten, and form crystalline structures.
  • Covalent compounds generally have lower melting and boiling points (because they have a volatile bond), insoluble in water, and doesn't conduct electricity because they don't have electrolytes
