Ionic Bonding and Properties

Which of the following is a property of an ionic compound?

• high melting point
• soft
• malleable
• liquid at room temperature

Ionic compounds have high melting points because

• An ionic lattice is a repeating pattern of ions with an ordered structure
• The ions cannot move
• a large amount of energy is required to break the ionic bonds in the lattice 
• There are no free electrons
