principals of chemistry

• 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
• metals

  • conduct heat and electricity
  • malleable
  • shiny
  • high melting point
  • ductile
• non-metals

  • no conduct heat and electricity
  • dull
  • low melting point
  • brittle
