Ions and Ionic Bonds

• Chemical bond formed by transfer of es from one atom to another
• Metals lose es to form cations, non-metals gain es to form anions
• Positive cations & negative anions attract to each other
• Strong electrostatic force of attraction between positive cations and negative anions is called ionic bonding
• Ion Property: Form giant lattice

  Reason: Cations and anions attract
• Ion property: High m.p. and b.p.

  Reason: Strong bonds between ions
• Ion property: Don’t conduct electricity when solid

  Reason: Ions can’t move
• Ion Property: Conduct electricity when molten/aqueous

  Reason: Ions can move
• Ion Property: Usually soluble in water

  Reason: Not required
