Ionic Compounds Flashcards
What holds together an ionic compound’s giant structure?
Strong electrostatic forces of attraction between oppositely
charged ions.
What is the force that acts in all directions in an ionic compound lattice?
lonic bonding.
How can the structure of sodium chloride be represented?
In various forms, such as dot and cross, ball and stick, and two or three-dimensional diagrams.
What should students be able to deduce from a diagram of an ionic compound’s structure?
That the compound is ionic.
What limitations should students describe when using diagrams to represent a giant ionic structure?
Limitations of dot and cross, ball and stick, and two or three-dimensional diagrams.
What should students be able to work out from a given model or diagram showing ions in an ionic compound’s structure?
The empirical formula of the ionic compound.
Is it necessary for students to know the structures of other ionic compounds?
No, they should be familiar with the structure of sodium chloride but not other ionic compounds.
