Ionic Bonding
Flashcards do conjunto (8)
- 1Identify the type of elements that make up ionic compounds?Ionic compounds are made from metal and non metal ions
- 2What 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.
- 3Name the structureThis is a giant ionic lattice.
- 4Why do ionic compounds form lattice structures?The positive ions (cations) align themselves next to the negative (anions) to form a lattice structure.
- 5Why 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.
- 6Do ionic compounds conduct electricity when solid?NO! there are no free charges to allow the conduction of electricity
- 7Do ionic compounds conduct electricity when molten (liquid)?YES! There are free charges that allow the conduction of electricity.
- 8Do ionic compounds conduct electricity when aqueous (liquid)?YES! There are free charges that allow the conduction of electricity.
