|
Ionic compounds have regular structures (giant ionic lattices) in which there are strong electrostatic forces of attraction in all directions between oppositely charged ions. |
|
Describe the structure of an ionic compound? Practical dissolving different types of ionic compunds and covalent compunds and testing if they conduct electrcity.
EW: Compare and contrast the properties of ionic and covalent compounds. |
|
|
|
These compounds have high melting points and high boiling points because of the large amounts of energy needed to break the many strong bonds. |
|
Explain why ionic compounds have high melting and boiling points? |
|
|
|
When melted or dissolved in water, ionic compounds conduct electricity because the ions are free to move and so charge can flow. |
|
Under what conditions are ionic compounds able to conduct electricity? |
|
|
|
Knowledge of the structures of specific ionic compounds other than sodium chloride is not required. |
|
What are the structures of different ionic compounds? |
