Ionic Bonding

• Ions are charged particles formed when atoms gain or lose electrons.
• Ionic bonds are formed between a metal and non-metal
• Ionic bonds transfer their electrons.
• Magnesium transfers

  2 electrons to oxygen, which means oxygen gained 2 electrons.

  
• Giant ionic lattices are regular structures, held together by ionic bonds.
• The giant ionic lattice is made up of positive and negative ions arranged in a regular pattern.
• Ionic substances have high melting points because the electrostatic force of attraction between oppositely charged ions is strong
• Ionic substances require a lot of energy
• What is ionic bonding?

  It is the electrostatic attraction between positive ions and negative ions
• How are ionic compound held together?

  They are held together by a giant lattice.
• An ion is atom that loses or gains and electron and therefore has a positive or negative charge
• Describe what has to happen for metals and non-metals to become ions

  Metals lose electrons, non-metals gain electrons.
• An ionic compound is a giant structure of ions. Describe how it is held together?

  Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions. These forces of attraction act in all directions.
