• 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

Ionic compounds can conduct electricity as a solid

• true
• false

An ionic compond dissolves when

• ionic bonds are broken
• the ionic lattice becomes disordered
• the ionic lattice collapses
• the ions are completely separted by the water molecules in the solution
