level questions: Ionic bonding
| Question | Answer |
|---|---|
| Definition of ionic bonding | Electrostatic attraction between oppositely charged ions |
| Things to remember in dot and cross diagrams | - square brackets [] - can put a big 2 or n number infront of brackets - remember the charges on the outside of [] |
| Structure of an ionic compound | each ion attracts oppositely charged ions in all directions resulting in a giant ionic lattice. |
| Properties of ionic compound | -solid at rtp due to insufficient energy to overcome the strong electrostatic forces of attraction between oppositely charged ion . so high temp needed so HIGH MELTING AND BOILING POINT -soluble in polar solvents (charged) - Electric conductivity inn liquid state as ions are delocalised and free to move as charge carriers |
