3.1.3.1 Ionic bonding.

• What is the definition of ionic bonding?

  A type of bonding that occurs between metal atoms and non metal atoms, their atoms exchange electrons.
• What do metal atoms do in ionic bonding?

  Metal atoms lose electrons to fill their outer shell and form positive charged ions.
• What do non-metal atoms do in an ionic bond?

  Non-metal atoms gain electrons to fill their outer shell and form negatively charged ions.
• When does ionic bonding occur?

  When oppositely charged ions attract strongly to create a lattice. (Electrostatic attraction.)

  -->The arrangement of the lattice results in the ionic compounds having a high melting and boiling points.

  --->Many strong bonds need to overcome.
