Frage | Antworten |
Identify the type of elements that make up ionic compounds? | Ionic compounds are made from metal and non metal ions |
What can be said about the boiling points of ionic compounds? | Ionic compounds have HIGH melting and boiling points because a lot of heat energy is needed to break the ionic bonds. |
Name the structure | This is a giant ionic lattice. |
Why do ionic compounds form lattice structures? | The positive ions (cations) align themselves next to the negative (anions) to form a lattice structure. |
Why are ionic structures brittle? | When hit, the layers move over each other. This means that positively charged ions lie above positively charged ions. These repel each other. |
Do ionic compounds conduct electricity when solid? | NO! there are no free charges to allow the conduction of electricity |
Do ionic compounds conduct electricity when molten (liquid)? | YES! There are free charges that allow the conduction of electricity. |
Do ionic compounds conduct electricity when aqueous (liquid)? | YES! There are free charges that allow the conduction of electricity. |
