Ionic Bonding

Ionic Bonding – Transferring electrons
1. In Ionic Bonding, atoms lose or gain electrons to form charged particles (called ions) which are strongly attracted to one another (because of the opposite changes + and -)
  1. A shell with just one electron is well keen to get rid of it extra one electron to complete it shell
    1. Become a positive change (E.g. Na+)
  2. A nearly full shell is well keen to get that extra electron from another atom that has an extra electron the it ‘wants’ to get rid of, so it can have an complete shell
    1. Become a Negative change
Ionic compound has a regular lattice structure
1. Ionic compound always have giant ionic lattices
2. Ions form a closely packed regular lattice arrangement
3. Electrostatic forces of attraction between oppositely charge ions, in all directions.
Ionic compounds all have similar properties
1. They all have:
  1. High melting point
  2. High boiling point due to strong electrostatic attraction between the ions
  3. Ions as are free to move when dissolved or melted in water so the substance can be electrolysed
  4. CANNOT conduct electricity as a solid but CAN in aqueous solution or when molten
  5. Dissolve easily in water
