  • IONIC BONDING (Transferring Electrons)
    • Atoms lose or gain electrons to form charged partiles ) called ions) which are then strongly attracted to one another ) because of the attention of the opposite charges + and -
    • If the atom has one electron in it's outer shell - it wants to get rid of it - after getting rid of the electron it will be an ion IT WILL BECOME POSITIVELY CHARGED
      • A nearly full shell is keen to get the extra electron  after it gains the electron it will be an ion.  IT WILL BECOME NEGATIVELY CHARGED
    • Regular Lattice Structure (Giant)  with very strong electrostatic fores of attraction between opositely charged ions
    • Ionic Compounds have similar properties
      • HIGH MELTING POINT ( due to strong attractions between ions, it takes a large amount of energy to overcome attraction )
      • When the electrons are free to move, they will be delocalised and will carry electric current
      • Dissolve easily in water  - ions separate - delocalised - carry electric current
