Ionic compounds conduct electricity when dissolved in water. Which statement below best explains the property?
Ions are free to move.
Electrons are free to move.
Bonds are strong.
There are weak intermolecular forces of attraction.
Which three of the following are features of ionic compounds? (click 3 boxes)
They have bonds between metals and non-metals.
They have bonds between two non-metals.
They form simple molecular structures.
They form giant ionic lattices.
They involve the transfer of electrons.
Ionic compounds form giant ionic lattices. What forces hold the giant ionic lattices together?
strong frictional forces between the surfaces of the atoms
strong magnetic forces of attraction between the poles of ions
strong electrostatic forces of attraction between oppositely charged ions
Why do ionic compounds have high melting and boiling points?
Their ions are free to move.
Their ions are held in fixed positions.
They have many strong bonds.
They have many weak bonds.
True or false? Ionic compounds have high melting points.
true
false
True or false? Ionic compounds have low boiling points.
true
false
True or false? Ionic compounds conduct electricity when they are in their solid state.
true
false
Why do ionic compounds NOT conduct electricity when they are in their solid state?
Their ions are free to move.
Their ions are held in fixed positions.
Their electrons are free to move
Their electrons are held in a fixed state
Why do ionic compounds conduct electricity when they are molten or dissolved?
Their ions are free to move.
Their ions are held in fixed positions.
Their electrons are free to move
Their electrons are held in a fixed state
Magnesium oxide is insoluble in water. Can magnesium oxide conduct electricity?
Select yes or no and a reason.
Yes
No
Magnesium oxide can be heated so that it melts and conducts electricity.
Magnesium oxide doesn't dissolve, so it stays in its solid state and doesn't conduct electricity.
