They must be made of ions with like charges.
The negative ion must be written first.
Compounds must have an overall charge of zero.
They are made of metals and nonmetals.
The positive ion must be written first.
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
What properties does an ionic compound have?
A low boiling point and it conducts electricity when dissolved in water
A high melting point and it conducts electricity when molten or dissolved
A high boiling point and it conducts electricity when solid
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.
