Which properties are all characteristics of ionic compounds?
solids with high melting and boiling points
soft solids which are highly malleable
when solid, the ions are held in place so the compounds cannot conduct electricity
conduct electricity when dissolved or molten
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
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.
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 which require a large amount of heat energy to overcome these strong bonds.
They have weak bonds which require a little amount of heat energy to overcome these weak bonds.
Be and F can combine to form BeF2, an ionic compound. Select ALL the true statements.
Each Be atom loses two electrons from the outer shell.
