Ionic bonding

Cards (9)

What is ionic bonding?
Involves the transfer of electrons from a metallic element to a non-metallic element
What is the ionic bond?
The electrostatic attraction formed between the oppositely charged ions.
How is ionic bonding non-directional?
the electrostatic attractions occur in all directions.
Why do ionic compounds have high melting points?
The electrostatic attractions are very strong and require a lot of energy to overcome.
What is the structure of an ionic lattice?
Repeating pattern of positive and negative ions which cancels out the charges so the lattice is neutral overall. The lattice is an evenly distributed crystalline structure.
What are the properties of ionic lattices?
High melting point, brittle, conduct electricity when molten or in solution.
Why are ionic lattices brittle?
When pressure is applied, the displacement causes ions with like charges to come close together and repulse so the structure shatters.
Why can ionic lattices only conduct electricity when molten/aqueous?
The ions are free to move and carry the charge throughout the structure.
Why do ionic substances have high mp and bp’s?
Strong electrostatic forces which require a lot of energy to overcome.
