level questions: Properties of ionic compounds

Question	Answer
The arrangement of ions in a regular lattice structure, forming a giant ionic lattice.	Structure of Ionic Compounds
How are the properties of ionic compounds influenced?	The properties of ionic compounds are affected by their structure.
Three-dimensional structures formed by the repetitive arrangement of positively and negatively charged ions in ionic compounds.	Giant Ionic Lattices
What type of structure do ionic compounds typically have?	Remember that ionic compounds have a regular lattice structure, known as giant ionic lattices.
Strong forces of attraction between oppositely charged ions in an ionic compound, acting in all directions.	Electrostatic Forces of Attraction
What forces hold the ions together in an ionic compound?	Strong electrostatic forces of attraction act in all directions between the oppositely charged ions.
The temperatures at which a substance changes state from solid to liquid (melting) or from liquid to gas (boiling).	Melting and Boiling Points
Why do ionic compounds have high melting and boiling points?	Lots of energy is needed to break these strong ionic bonds, giving ionic compounds high melting and boiling points.
The ability of an ionic compound to conduct electricity.	Conductivity of Ionic Compounds
Under what conditions do ionic compounds conduct electricity?	Ionic compounds also conduct electricity if they're molten (melted) or in aqueous solution (dissolved in water).
The state of matter in which a substance has melted and become a liquid.	Molten State
Why do molten ionic compounds conduct electricity?	This is because the charged ions in a molten or dissolved ionic compound are free to move.
A solution in which water is the solvent, with ionic compounds dissolved in water.	Aqueous Solution
How do dissolved ionic compounds conduct electricity?	Ionic compounds also conduct electricity if they're in aqueous solution, as the charged ions are free to move.
Charged ions that are free to move within a substance, such as in molten or dissolved ionic compounds.	Moving Charged Particles
What allows for the conduction of electricity in molten or dissolved ionic compounds?	These moving charged particles allow an electric current to flow.
The flow of electric charge through a conductor, resulting from the movement of charged particles.	Electric Current
What is facilitated by the movement of charged particles in molten or dissolved ionic compounds?	These moving charged particles allow an electric current to flow.
