4.3 The ionic bond Flashcards
1
Q
What is the ionic bond?
A
The ionic bond is the bond that forms between ions of opposite charge.
2
Q
What is an ionic compound?
A
An ionic compound is made up of ions held together by strong ionic bonds. They form a regular pattern or lattice of alternating positive and negative ions.
3
Q
What does a metal react with to form an ionic compound?
A
A metal reacts with a non-metal to form an ionic compound. The metal atoms lose electrons. The non-metals gain them. The ions form a lattice. The compound has no overall charge.

Q
What should you do to show bonding clearly in bonding diagrams?
