Ionic Bonding

Why do atoms form Bonds?

  • Atoms with an outer shell of eight electrons have a stable elctronic structure
  • Atoms can be made stable by transferring electrons. This is called ionic bonding
  • Metal atoms lose electrons to get a stable electronic structure
  • If an atom loses electrons, as positive ion is formed
  • Non-metal atoms gain electrons to get a stable electronic structure
  • If an atom gains electrons, a negative ion is formed
  • During atomic bonding, the metal atom becomes a positive ion and the
