Ionic Compounds Flashcards
What structure do ionic compounds have?
Ionic compounds have a structure called a giant ionic lattice.
How are giant ionic lattices formed?
They are formed when ions form a closely packed regular lattice arrangement and there are very strong electrostatic forces of attraction between oppositely charged ions in all directions of the lattice.
Why do ionic compounds have high melting and boiling points?
Because of the many strong bonds between the ions - it takes a lot of energy to overcome this attraction.
Why can’t ionic compounds conduct electricity?
This is because it is in solid form, meaning that the ions are held in place so the compounds can’t conduct electricity.
When can ionic compounds conduct electricity?
When it is melted or dissolved in water - when dissolved in water the ions separate and are all free to move in the solution, so they will carry electric current - when melted the ions are free to move and they will carry electric current.
