A regular lattice structure.
5
Q
What properties do all ionic compounds have?
A
High melting and boiling points due to a strong attractions between the ions.
6
Q
What is there between oppositely charged ions?
A
Strong electrostatic forces of attraction.
7
Q
What happens when ionic compounds melt?
A
Ions are free to move and will carry an electric current.
