• Are an electrostatic force of attraction • It only occurs between metals and non-metals • Metals always LOSE electrons, non-metals always GAIN electrons
Giant ionic lattices, melting and boiling points are...
High - strong electrostatic forces of attraction exist between all ions in the lattice that require a lot energy to overcome.
Do giant ionic lattices conduct electricity?
Yes - ions are present to carry charge and conduct electricity (only conduct electricity when in water).
Are giant ionic lattices soluble in water?
Yes - ions are present and can be pulled apart (dissociate themselves from water).
Oxidation is loss of electrons and reduction is gain of electrons.
Ionic bonding is...
A strong electrostatic attraction between oppositely charged ions.
An ionic crystal is....
A giant three-dimensional lattice structure held together by the attraction between oppositely charged ions.
What is required in order to conduct electricity?
Ions - in order to carry charge.
What does the structure of sodium chloride look like?
giant ionic lattice structure - ions are held together in a closely packed 3D lattice arrangement by the attraction between oppositely charged electrons
What is the relationship beteen ionic charge and the melting and boiling point of an ionic compound?
- The higher the differece in charge, the stronger the attraction will be.
+ and - ions will have a weaker charge than 3+ and 3- ions
- The stronger the attraction, the harder it is to break the bond and so the melting and boiling points are higher.
- The bigger the charge of an ion, the higher the melting and boiling point.
