Ionic Bonding

- 1It occurs when there is a metal and a non-metal atoms cannot gain or lose more than 3 e metals lose e to form +ions non-metals gain e to form -ionsatoms try to achieve a stable EC of the noble gases
ions attract each other to form a giant lattice.
the attraction of the oppositely charged ions is the ionic bond - 2Ions are charged particles Soild ionic compounds exist in a giant lattice. Current is a moving charge. Solid ionic compunds cannot conduct electricity because the ions are not free to moveTo make ionic compounds conduct we must turn them into liquids.
We either add water to the compound or we melt it - 3once the compound is liquid the ions are now free to moveThe positive ions move to the negative electrodes
The negative ions move to the positive electrode
