Unit 5 Name _______________________________ # ________
1. Why does a high electronegativity difference lead to ionic boning?
2. Describe what happens in an ionic bond.
In each empty cell, fill in the different atom types and state how many atoms there are of that type. If there are no more atom types, put N/A in the other cells in that row.
