- 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
