ionic bonding

• Ions do not conduct electricity when in a solid state because the ions are not free to move and carry charge
• Ions have a high melting point as they are made up of giant ionic structures lots of energy is needed to break the millions of ionic bonds
• Model Ionic binding answer:

  Lithium loses 1 electron and forms a 1+ ion. Fluorine gains this electron and forms a 1- ion. Opposite charged ions attract electrostatically to each other. This is an Ionic bond
• how to do ionic bonding equations?

  • write your symbols
  • assign the charges
  • drop and swap the numbers but not the charges
  • if the numbers can be cancelled down, do so
• ionic bonding occurs when a metal and nonmetal react, metals form positive ions and nonmetals for negative ions
• Ionic compounds are held together by electrostatic forces between the oppositely charged ions
• ionic compounds are in a giant lattice structure and are held together by strong electrostatic forces of attraction between oppositely charged ions
• how are ions made?

  when a metal atom reacts with a non-metal atoms, electrons in the outer shell of the metal atom are transferred. metal atoms lose electrons to become positively charged ions. non-metal atoms gain electrons to become negatively charged ions
• ions produced by metals in group one and two, and non-metals in group 6 and 7 have the structure of a noble gas
• what are ionic compounds?

  • a giant structure of ions help together by strong electrostatic forces of attraction between the oppositely charged ions.
  • the forces act in all directions in the lattice via ionic bonding
• what are the properties of ionic compounds?

  • high melting and boiling points due to the many strong bonds that need a lot of energy to overcome them
  • only conduct electricity when melted because ions are free to move through the structure.
  • some can dissolve in waters can carry electric charge within a solution
