Properties of Ionic compounds

What makes up an ionic compound?

• Negatively charged metal ions only

• Positively charged metal ion and negatively charged non-metal ions

• Positively charged non-metal ions only

• Both positively and negatively charged metal ions

What holds the ions in a giant ionic lattice together?

• Magnetic forces

• Weak electrostatic forces

• Gravitational forces

• Strong electrostatic forces

Why do ionic compounds have high melting and boiling points?

• Molecular structure

• Low amount of energy needed to break the lattice

• Strong ionic bonds

• Weak ionic bonds

What allows ionic compounds to conduct electricity when molten?

• Ions are held in fixed positions

• Ions cannot carry their electrical charge

• Oppositely charged ions start to move

• Ions lose their charge

Why can't ionic compounds conduct electricity when solid?

• The lattice breaks up

• Ions lose their electrical charge

• Ions can move freely

• Ions are held in fixed positions

What happens to the ionic lattice in a solution that allows it to conduct electricity?

• The ionic lattice splits up

• The ionic lattice turns into a metallic lattice

• The ionic lattice becomes stronger

• The ionic lattice remains unchanged

What is the structure of ions in an ionic compound?

• Circular arrangement

• Giant structure arranged in a lattice

• Single line

• Random arrangement

What direction do the forces of attraction act in an ionic lattice?

• No specific direction

• In all directions

• In two directions

• In one direction

What is needed to break up a giant ionic lattice?

• Water

• A small amount of energy

• Magnetic force

• A large amount of energy

Why are ions in a solid ionic compound unable to conduct electricity?

• They are not charged

• They dissolve in the solid

• They can only vibrate on the spot

• They can move freely
